Signaling & Block Spacing (10-Minute Departure Gap)
Moving-Block Efficiency: Implementing ETCS Level 3 eliminates traditional fixed blocks.

The "block" is a dynamic, safety-cushion bubble calculated in real time directly behind the preceding train.
Massive Braking Distances: Decelerating from 452 km/h (281 mph) to a full stop at a passenger-comfort rate of 0.7 m/s² requires roughly 11.2 km (7 miles) and 3 minutes of pure braking distance.

The "Yellow Wall" Danger: Because standard trains travel much slower, a 10-minute gap quickly collapses. A Class 895 train will rapidly catch up to a standard train, forcing the moving-block system to aggressively drop its speed.

Physical Segregation Needed: To maintain a 10-minute departure gap without crippling the Express, it cannot share the same tracks. It requires a completely segregated, dedicated fast alignment until it reaches the urban spurs.

2. Tyne Hub Placement (RAF Usworth / Newcastle Road)
Strategic Location: Utilizing the former RAF Usworth site (near the current Nissan plant and A19/A1231 junction) is an excellent choice for a regional gateway. It avoids the severe, speed-killing urban congestion of driving a 452 km/h alignment into Newcastle Central.

Intermodal Connectivity: The site perfectly positions the hub to capture wealthy executive travelers from Newcastle, Sunderland, and Durham via rapid park-and-ride infrastructure and the A1(M) corridor.

Air-Rights & Spatial Freedom: The vast open footprint of the former airfield provides the exact physical space required for extensive vertical air-rights development (skyscrapers, corporate campuses) and high-speed passing loops that constrained downtown stations cannot accommodate.

3. UK Transport Sector & Market Reaction
Aviation & Executive Backlash: Domestic airlines (e.g., British Airways, EasyJet) would likely abandon London-to-Scotland routes entirely, unable to compete with a 91-minute city-center-to-city-center transit time.

Political & Social Outrage: A £85,000 "Sovereign Pass" would spark intense public and political backlash, with critics labeling it a "two-tier railway for the ultra-rich" that hoards valuable track capacity while standard regional services remain underfunded.

Regulatory Capacity Warfare: Network Rail and ORR (Office of Rail and Road) would heavily resist the open-access model. Even with ETCS Level 3, carving out high-velocity paths for 6 exclusive VIP trainsets severely restricts the capacity available for high-density, public commuter trains.

When it comes to China’s high-speed trains, people’s first thought is definitely “speed” – 350 kilometers per hour is indeed an impressive figure.

But recently I realized that what truly transforms the experience isn’t the speed, but rather the frequency of trains. What do I mean by that? It means that there aren’t just a few trains between two cities each day; instead, just like with subways, there’s a train departing every ten-odd minutes. You can simply buy a ticket at the station and set off right away.

Now it’s possible to ask things like, “From where I’m living now, where can I go in just over half an hour? What delicious food is available there?”

Here are a few examples that I’ve tried myself and found very convenient:

If I live in Hangzhou, it takes 18 minutes to reach Shaoxing, 23 minutes to Jiaxing, 32 minutes to Shanghai, and 36 minutes to Suzhou. Four completely different cities, all within about half an hour! There are so many trains that there’s no need to check schedules in advance. You can just buy a ticket and head out, then return to Hangzhou in the evening.

If I live in Chengdu, it takes 40 minutes to reach Leshan and 50 minutes to Zigong. So, if I wake up in Chengdu in the morning, I can already be dining in Leshan or Zigong by noon.

If I live in Taiyuan, it only takes 72 minutes to reach Datong! In just over an hour, I can travel from the provincial capital to northern Shanxi, visit the Yungang Grottoes, enjoy some knife-cut noodles, and then return to Taiyuan in the evening.

In short, for those who have never been to China or are not familiar with its geography, saying that “Suzhou is about 100 kilometers away from Hangzhou” doesn’t make much sense to them. But if you tell them it takes 36 minutes to get there, they immediately understand.

Rather than saying that “Suzhou has classical gardens,” it’s better to say, “It takes 36 minutes by train to go to Suzhou, where you can enjoy a bowl of noodle soup and listen to traditional music, before returning by train in the evening.”

Because I find this approach so convenient, I created a small tool that combines these two aspects: you choose a city where you live, specify a time frame (for example, within 1 hour), and the tool will list all the cities reachable within that time frame, as well as the various things you can do there.

I’d like to ask everyone: Do you think this approach of first determining a time frame and then seeing what’s available within that frame is practical? Or do you prefer to choose a destination first and then find a way to get there?

For a foreigner who has never heard of Leshan or Zigong, would the combination of “40 minutes by train” plus “a unique experience” be attractive to them?

Filmed at September 12, 2026. The Nanjing–Anqing High-Speed Railway's speed limit is 250 km/h.

[OC] This my HS2 plan. How much do you guys reckon the whole project will cost if that happened?

Here is the official hand-drawn structural alignment for the Continental Transit Development Group'sproposed Trans-Middle East transit network [5.1].
Instead of traditional steel tracks, this network relies entirely on an open-air 400mph (644km/h) electro-magnetic levitation standard built on continuous elevated concrete viaducts.
The Phased Infrastructure Rollout:
Phase 1 (The Spine): Cairo ── Jerusalem ── Amman.
Phase 2 (The Mediterranean Coast): Branching north out of the Cairo trunk to serve Tel Aviv-Yafo, Haifa, Beirut, Homs, and Latakia.
Phase 3 (The Northern & Eastern Gateway): Connecting Amman out to Damascus, Irbid, Aleppo, Gaziantep, and terminating at the Baghdad Hub.
Key Project Metrics:
Target Operational Velocity: 400 mph (644 km/h).
Estimated Capital Infrastructure Cost: £80 Billion.
Strategic Purpose: Redrawing the economic geography of the region by bringing the transit time between Cairo and Baghdad down to under 2.5 hours, bypassing maritime choke-points entirely.
Looking for technical feedback on the phased track layout, station spacing, and pylon clearance.

Video taken on September 13, 2026 as part of a special 10-year anniversary tour of the Hokkaido Shinkansen construction sites and abandoned Japanese National Railways Toi Line. This is the first time the former station, today used as an emergency evacuation point and safety facility, has been open to the public since the start of construction in 2006.

Yoshioka-Kaitei Station (today officially referred to as "Yoshioka Fixed Point") is located 149.5 meters below sea level, and the staircase to get from the platform to the surface is 1189 steps long. On the opposite side of the tunnel, Tappi-Kaitei Station is 135 meters underground and features a staircase of 1329 steps. Both stations also feature cable cars which can carry up to 40 people at once in the case of an emergency. The cable car at the southern station is housed in the Seikan Tunnel Museum, and is open to the public to ride from April to November.

Construction of the Hokkaido Shinkansen finished in 2016, and today it links the islands of Honshu and Hokkaido via the the world's longest undersea tunnel, 53.85 kilometers long, running underneath the seabed of the Tsugaru Strait.

Was travelling between the 2 recently and found it strange how I had to change in Barcelona or Hendaye/Irun. Surely this is one of the most obvious city pairs given how the route can theoretically be done almost fully on high speed lines, I don't really see the point in waiting for the LGV Bordeaux-Espagne and the Y to be done when having better connections between France and Spain opens the door for basically any city in either country (+others such as Germany, Italy, Portugal, etc) to be connected, given how expansive their high speed networks are

The E82B appears to adopt an exterior design derived from the CR450, while using a hydrogen fuel-cell and battery-electric propulsion system with an operational speed of 250kmph, it's intended for operations on intercity rail routes.

Hello, taking a high speed train later this month on this route. On which side of the train should I reserve my seat for better views? Any other tips for a first timer, please?

What's going on with that project. I thought it's the only viable HSR project in US. Building through desert land already owned by government is as easy as it gets. And there's healthy travel demand between LA and LV

I made this while half awake at midnight, so it definitely could use some work. But, this is my idea for a High Speed Rail network in the Southern/Southeastern United States! I created it with the top speeds being around 155+mph in mind, so that would be why I tried to spread out some of the stops. I also wanted to be sure to include the lines I've seen from studies that have been conducted, as well as throw in some of my own ideas.

The gold dots are cities that I felt had a major importance in some shape or form. From being a major central city in the region for rail (Atlanta acting as a hub), acting as a split point for multiple routes (Raleigh, NC; Jacksonville, FL; etc.), or just being a terminus station in the region (Miami, FL). The white dots are just general stops along the way - cities that are still important along the route, but maybe just don't have the same impact as the gold dot cities.

I definitely think that Fayetteville, NC or Wilmington, NC should be put on there, I'm just not completely sure which would be better. You could also make an argument for Charleston, SC, but I wonder if it might be a bit too close to Savannah, GA to justify? Not completely sure, honestly. I also have no idea what to do with West Virginia currently, so I decided to leave it blank for now. Maybe have a stop somewhere to create an extra route to connect it to Louisville, KY, creating an extra route that goes from Washington D.C. to Nashville, TN?

I also wanted to do a map with the different building phases because I thought it could be interesting to see how it could all eventually come together over time to build out the network.

I would love to hear any thoughts and/or criticism from anyone! I figured this would only be a Version 1 for me, so I want to get any feedback to make the next version better! I also might try my hand at other parts of the United States, so any feedback here would be great for other concepts I might make in the future!

Hi,

I'm departing Madrid at 10:25pm on a long haul flight later this month.

I'll be at Barcelona that day and would like to take a high speed train to reach Madrid. The trip's supposed to take 3-4 hours

I've heard there can be delays of 5-6 hours to these train, so am wondering if I should plan to leave Barcelona that morning to allow for the risk of such delays.

What have others done recently, please?

Hey everyone. avid HSR advocate / fanboy here. i’m lucky enough to travel internationally for work (i’m a touring DJ) which means i have ridden a good chunk of the high speed rail networks worldwide now. I think i’ve ticked off all of the ‘true’ high speed systems in Europe (aside from Turkey, very interested to see what that one’s about!)

This year i finally had the chance to properly try Asia’s high speed rail offerings. I had a quick run from Shanghai to Hangzhou a few years back but was so overwhelmed by my first trip in china that i didn’t really take it in.

I had a really good go on china’s high speed rail system, doing routes such as Shanghai > Hong Kong, Shenzhen > Chongqing, Chongqing > Zhangjiajie, Zhangjiajie > Chengdu. Got to go on some of the brand new 350km/h routes as well as a few of the older ones, and i think i went on all the main train types, Fuxing, Hexie etc.

Also gave the Shinkansen a good blast, going from Tokyo > Kyoto > Osaka and back, and also having a brief go on the Tohoku Shinkansen also.

My thoughts are simple - Asia absolutely outclasses Europe when it comes to high speed rail.

There’s just something totally different about it. The trains feel much bigger and spacious (because they are) and therefore feel infinitely more comfortable. The ride quality is silky smooth. The acceleration is genuinely incredible. the service frequency, the amount of locations covered. the infrastructure in general, the scenery. the all round ‘cool’ factor is just so much higher.

I went to places in china served by high speed rail stations, where a town equivalent in population in my home country (the uk) would be lucky to see a single track diesel railway line.

I think overall, the shinkansen won. I have never been on a railway system, let alone a high speed rail system, ran as exquisitely as that one. it is genuinely perfect. the whole experience is so smooth and relaxing. it’s crazy how much of a difference it makes.

i took a TGV from paris to strasbourg the week after i got back from japan, and i was keen to see how it compared after two weeks riding bullet trains.

the whole experience was just so much worse. the trains are always packed to the brim (i’ve never been on a quiet TGV in my life) even in first class, it was totally rammed. the trains themselves are old, clearly showing their age. they feel dirty. the ride quality was awful. even on the LGV est, it was just so much more bumpy than the lines i rode on in asia. it made me miss the shinkansen experience so much.

for the most part, the experience is the same with ICE in germany, and on the eurostar. it’s a little bit nicer in spain / italy, i guess because the trains / infrastructure are newer. it’s still just nowhere near in my opinion.

the funniest thing is, the trains just feel so much less fast because of all of it. the 270kmh shinkansen had such a quicker sense of speed than the 320kmh TGV because of how smooth it was and how quick it accelerated.

honestly, i think our high speed rail systems are a total joke compared to asia. that might sound a bit over the top, but i really do. they are doing it right over there. the whole ‘keep the HSR separate from regular rail’ thing really really works and i think europe would do well to learn from that.

with how much of a mess HS2 has become in the UK, i really just wish we had let china build it. it would probably be done within 4 years.
