But these guys had it in the bag.
You can't. It might be possible with a diesel-hydraulic.
You could - with a DC main gen -, if you had enough residual magnetism in the TM field coils or had enough oomp in the batteries to provide some magnetic field.

We tried it one day, using another locomotive. Rail was wet, so it didn't work and we ended up jump-starting it.

Умом Россию не понять translates as "Russia does not understand the mind" (it rhymes) but roughly means "Russia is full of dumb people." There are a number of videos on the web under that heading showing stupid signs, etc. Russian humor is of the "laughing through tears" variety, about corruption and the failures of society. BTW that unit is likely the descendant of the ALCO RS1s that we gave the USSR under lend lease and that they copied exactly.
Maybe it's a stick shift...............
Betcha hafta use both legs to push the clutch pedal in.
No, you cannot start a diesel electric by pushing it. No way. To use residual magnetism in the motors, you would have to reconfigure some relays and switch gear to have the motors power the generator, the generator to act like a motor, and so turn the crankshaft. The switchgear on the locomotive is configured for the generator to power the motors, not the reverse. (Polarities would require reversal, the generator field coils vs the armuture on a dc generator locomotive. On an SAC generator locomotive, the rectifiers and any ac motor frequency invertor equpment are in the way of the electric power reverse path. On locomotives with dynaomic brakes, the contactors and relays can have the motor feed the dynamic brake resistors but not the generator.
Drag it too far and pump too much fuel into the exhaust system. Pop the clutch. Bang. Is the muffler still good?
Pop the clutch~~~ BANG shreek UH OH , muffler bearing is blown out. Hope no one saw that.
Y6bs evergreen in my mind

I'd love to help push, but my back's already a little sore...
I don't know about push-starting, but if you couple up to something hard enough - you can shut em down!
The opinions expressed here represent my own and not those of my employer, any other railroad, company, or person.
You suppose they lost the jumper cables?
There was probably someone in the cab who started the motor.
Don Oltmand is right.
Not that you can do it on all locomotives with DC generators but on older GP-7 locomotives with dynamic brakes you could get the engine rolling, plug the motors put it in notch 1 (or manually pickup the battery field) and the generator will rotate (hopefully in the right direction). hopefully you have just enough battery voltage to keep the main power contactors and the B contactor picked up ! If not you must block them in with bits of wood. The reverser and braking contactor can be thown manually and will stay where it is put.
On non dynamic engines I would usually take some auto motive jumper cables and short the traction motor fields together taking the place of the missing braking contactor.
I need to qualify the fact that the only locomotives I've done this way are GP-7s and 9s , it may be possible to do it on others but I have no experience doing it.
Many DC locomotive generators are getting scarce , not because of scrapping or burning out . The EMD DC generators make excellent motors for conveyor belts and drilling rigs..

I'm surprised that four people could even move it.

~~ I wonder if the ease of moving the engine by hand is because of the very high quality roller bearings in the trucks ??
