The 28-5 export variant was built to pull freight trains that do not carry nuclear weapons or anything of that sort.

And basically, the driving controls are on the left side of the cab. And unlike British locomotives, the throttle control is on the left and the brake controls are on the right. And they are both painted white.

Keys to use:
Activation groups 1 and 2 control the reverser handle. if you are in the cab with the giant headlights, 2 is forward and 1 is backwards as shown by the reverser handle. In the other cab, its the opposite.

Throttle. If you look at the giant bus steering wheel, you'll notice that the longr white section is pointed directly towards you when the throttle is at 0. When it is at 100, it will face away from you.

Headlights.
Activation groups 3 and 4 control the headlights and tail lights at the side with the smaller lights.
Activation groups 5 and 6 control them in the the other cab.

And yes, its a locomotive that looks like a British Rail Class 47, but is painted like a Soviet locomotive on the inside and is probably used by the Democratic People's Republic of Korea.
