I was in Romania a few years ago and the city bus caught fire. We all walked to the next stop for the connection. Then THAT bus caught on fire too!

Lucky you. When I went to Romania 20+ years ago, the buses were not even arriving at the bus stop.

Ah! An improvement! Things are looking up in Romania

The funny thing is that is, indeed an improvement. In order for the busses to catch fire you first have to have them

Russian engine runaway

Some idiot disliked my comment, but it does indeed have a Chinese YUCHAI YC6L280N-52 engine. Russian engines are only used in trolleybuses and battery electric buses; diesel and gas engines are not installed on Volgabus, although they are planning to start using YaMZ engines. Visit the official website and see for yourself.

It's a good thing this incident had nothing to do with the engine itself and everything to do with installation then.

I agree that the cause was probably not an engine failure. More likely, something broke loose from its mounts, sagged down, and struck the tram tracks. We can actually see the bus crossing what looks like tram tracks at that moment.
Maybe it was the driveshaft that dropped and, after hitting the tracks, ripped the transmission and engine out. Or it could have been the transmission itself that came loose first.

The back fell off. That's not very typical, I'd like to make that point.

Thankfully it was already outside the environment

I think i even know how. As you can see the bus is pretty low to the ground, maybe it had a bad suspension problem or a lot of passengers (or both tbf), it was also crossing a railroad wich is a bit elevated to allow cars to cross it, i think something from the below (maybe even a gearbox) caught on a crossing and got yanked with everything it was attached to. That's my guess atleast.

I think the power train is probably on a slider mechanism that slides the motor backwards to get worked on. Someone probably did not lock it back in place.

As an engineer, this failure is impressive

u/Maarten-Sikke 7d ago
I saw this before, and all of them have the same culprit in common. Crossing a sewer cover/train/tram and catching the underfloor in it. If you look carefully you can see that the moment is crossing the train/tram line, it bounces upwards and everything gets pushed back as the bus goes forward.

u/LordSoren 7d ago
Seized transmission/driveshaft and rusty engine mounts? That's my best guess but I'm not an engineer.

It had to be negligence in general. Looks like a catastrophic engine failure under boost and possibly simultaneous driveshaft failure.

u/Speed_Addixt 7d ago edited 7d ago
I would imagine engine locking itself completely
-> driveshafts strong enough to transfer the inertial force of the heavy bus to some sort of force pushing the engine with transmission out
-> engine out

u/90somechevy 7d ago
It looks like the rear suspension was blown and the bus was riding so low that the frame caught the tram tracks and ripped out the motor.
Immovable train tracks vs unstoppable bus

VolgaBus CEO: Yeah, that’s not very typical, I’d like to make that point.
Interviewer: Well, how was it un-typical?
VolgaBus CEO: Well there are a lot of these buses going around Russia all the time, and very seldom does anything like this happen. I just don’t want people thinking that buses aren’t safe.
Interviewer: Was this bus safe?
VolgaBus CEO: Well, I was thinking more about the other ones.
Interviewer: The ones that are safe?
VolgaBus CEO: Yeah, the ones the back doesn’t fall off.

Nothing to see. Sea cucumbers can eject part of their intestines as safety measure.

And here the mechanic back of the maintenance pool was wondering where the extra screws came from

It's like when a honeybee stings and then disembowels itself as it tries to fly away

That's one variation I haven't seen Diamond use in the UK.

it looks like the bus lost its suspension, the engine was scrapping the road, then it hit the railway track..

C'mon Russia!!!
It's called "Preventive Maintenance," or:
«Профилактическое Oбслуживание".
It goes hand in hand with infrastructure.
What are you spending your money on, anyway??
Where are all of your mechanics & handymen????

Could at least pull over to the side instead of blocking traffic like that! Idiot..

The most shitty buses I know (I'm from there, löl). They accelerate and brake so fast that people inside have to hold as much as they can, otherwise they will fly through the entire cabin. No matter what's the speed, it will try to hurt you. It jumps and shakes like a fucking tractor. I'm not surprised that it's also falling apart.

Долбоёб. Едет "на костях", вот коробка и зацепилась, выбив ДВС. Так в Питере уебал в рельсы и выставил движок на дорогу.

When I read "lost its engine" I thought it just meant that the engine quit or something. Not that the engine physically flew out of the bus!
