Yes, they are made by Alsthom, you have an eagle's eye!

Tell me one thing. You do not intend that the tank has to wear a person ?
You told me that you want to use an ESP32. May be you know the M5Stack which contains an ESP32.
The good thing is that with an M5Stack you can use a shield for big Lego servo. Those are clever servo, they can go to an angle of course, but they can too run to continuous rotation. You can too order it to do a number of turns. What else, it can be used as an angle sensor.
I have a few M5Stack, wich I never succes to connect, but I am a dummy . . .
Anyway, I think this could be a good way for your project.
Here, some pictures and links :

Sorry for the link, I couldn't attach it.

I had thought with the ESP32 for the number of I/O it has and because it is faster / more powerful than the typical Arduino because in the end the number of sensors and actuators is significant.
This up to you, but think you have to adapt your motor to Lego pieces. But with a 3D printer, all is possible.
Now that we have cleared the ground for a bit, can you estimate the size of the tank ?
Don't worry, it is just to make my mind and try to start the BOM.

it would be about 31 x 16 cm.
I am afraid it will be not long enough to climb stairs.
Please, look at the #10 video above, https://www.robot-ma...train/?p=114339 .
In the video, at 2'32", you can see that the tank must be hold up by at least 3 steps edges. If you have a staircase at home, measure the distance between 3 steps edges.
No problem for the width, it can be as narrow as you want. He will have a little difficulty turning on the spot, but in a train, you can't turn much.
This tank is 67cm X 42cm , 1,5kg.

I have calculated that the real model must be 5 times larger to be able to overcome the steps of the train, ie 80 x 155 cm.
Well, this will be one the biggest robot tank !

Well, here is the BOM !
I have widely evaluated the number of pieces. With Lego, it is interesting to have additional parts for possible modifications.
