i think the second engine has to work more since compartment is connected with it.......isn't it?

If the second engine is shut off, the first engine does all the work. The engineer chooses how the load is divided and sets the throttles accordingly. For a long climb, he'll run all engines. That's why he has them. The rest of the time, he's likely to completely shut off one or more units because it's generally more efficient to run an engine at full load.

When two engines of same horse power are connected serially one by one and the control of the second engine is transferred to the first engine and a single driver is running the train then the load is equally distributed among both these engines and not on the second engine as you have stated.

No your thinking does not seem to be correct,the load is divided.for example when you are going on a bicycle and the wind comes from behind you have to apply less power.If two persons are pulling one jeep tied to a rope by pulling the rope then also the load is divided.You might have seen when two persons are pushing the bus in order to get the same started they are unable but when 5-6 persons are pushing the same bus then it becomes easy for them all.Similarly the two engines share the load where these are connected serially one by one.

It is a series connection. In series connection Total load = sum of loads shared by two engines (L1+L2) . This is a simple equation. Both engines share the load equally.

The load gets divided however it is designed. If one engine can deliver twice the horsepower of the other, and each is working at the maximum, one engine will carry two-thirds of the load, and the other will carry one-third, regardless of their positions.
If two people are pulling a load on a rope, each one pulls what they can, regardless of their positions.

they work together unless some are off. they are all controlled from the master engine.
