That looks like a fairly worn engine, and as if it has been idling for a long time, so lots of motor oil, gets up past the rings, and into the exhaust system (it's big) and coats it with hot oily crap..... You see these BIG engines will idle very slowly - because they have a HUGE direct drive armature coupled to them - it's a GIANT fucking flywheel....

AND being 2 stroke motors - I am not exactly sure of the slow idle fuel injection and firing sequence of say a V 12 or a V 16 motor, by I could make my OLD Harley idle at around 60 RPM, because it had HUGE flywheels.. and a low compression motor...

I THINK these can be set to make ONE combustion cycle every 4 or 8 RPM - per cylinder..

So the piston - being a 2 stroke, goes

"up and down"

"up and down"

"up and down"

"up and down"

"up and down"

"up and down"

"up and down"

"up and down"

"up ----- AND ------BANG! - a really weak injection of fuel ------ then down"

And the firing cycles are spread intermittently across all 8, 12, or 16 cyclinders.

So they all stay "running warm" - but the motor oil still works it's way up past the oil control and compression rings on the piston, to wet the insides of the exhaust system.

Especially if the motor is worn.

So when they sit there idling for a while, could be for an hour, could be 4 or 5 hours... These huge clouds of smoke are all that engine oil burning off the heads, piston crowns, exhaust valves, manifolds and the exhaust system, including the turbo charger etc....

AND the smoke is VERY bad..... It makes you quite sick.

Actually, this is the normal operation for these. The model is called ТЭ10М. When it was released in the mid 80s, it was the strongest train engine with its 2x3000hp power production. A few 1000 has been built from them, most of them are operated in Russia nowadays.

@Geri: Soviet motors?

@Geri: A lot of European countries make some really nice looking equipment. https://upload.wikimedia.org/w....ikipedia/commons/d/d

@Geri: What type of steel and what is it's thickness on the front of the cabin?

@Geri: Did you know that decisions have been made to build / refit locomotives with 4 or 6 smaller engines and alternator sets, running sidewards - like a front wheel drive car, instead of a single big engine and alternator. The ONE small engine uses very little fuel when idling, but it's enough to keep the other engines heated up - prewarmed for easy starting in very cold weather, and it can supply power to keep all the electricals on the locomotive running, and to drive the locomotive around by it's self and or with small loads when shunting etc... AND when one motor stops working, you have 3 or 5 spare....

@Geri: If you look up "locomotive" in the search function - there are some excellent videos. https://www.mgtow.tv/v/2fQKsp

@Geri: This is a favourite. In HD - C Class Loco C501 3300HP - Cab and engine room - "Trippin" start at 5:00 - then at 5:50 Big Engine working hard - long incline big load https://www.mgtow.tv/v/UDqjLf

@Life_N_Times_of_Shane_T_Hanson: I am not aware about specific details of the cabin. By the way a lot of freight locomotives are running in "always on" operation in various circumistances, because some for example needs the engine running to keep the breaking system pressurized.

@Geri: "Braking" - I thought the world over had the standard of "fail safe" brakes - when they fail, they fail in the safe state - or when the air pressure goes, the brakes come on. Otherwise when there is NO air pressure, you have the problem of rolling stock, and locomotives and passenger trains - simply rolling away when parked.

@Geri: https://en.wikipedia.org/wiki/....Westinghouse_Air_Bra AND ---- https://en.wikipedia.org/wiki/....Rail_transport_in_th ----- The Soviet Union made the transition to automatic brakes and couplers (model SA3) long after the United States did and as a result their brakes and couplers[41] were somewhat more advanced. Their (air) brakes could operate in a mode where it was possible to slowly reduce braking effort, while the US system required full release of the brakes (in the entire train) and reapplication of the brakes in order to reduce braking effort.[42]
