How to make a sprite appear in a specific location

[evepoi]

The sprite of the train GRF that we are making now is mainly driven by driving vehicles and passenger vehicles.

There are also graphics with pantographs in passenger vehicles. Of course, it is not a powered vehicle.

I have a question here.

We are setting up to be able to configure the train automatically in the game.

It is set in the order of driving vehicle, passenger vehicle, and driving vehicle.

How do I use a passenger vehicle with a pantograph on the 2nd and 3rd lights in the same way before and after it is set?
