So far my best attempt at a car-transporting train car. I originally wanted it to be able to load on both sides, but that turned out to be too hard so only the left side does. Inside there is a height limit of 10 blocks and a width limit of 13 blocks. The inside part is also 81 blocks long, meaning it can fit up to 2 or 3 cars, depending on the size of them. The controls for the loading process can be found on the front rails of the train car, and the buttons must be pressed in order from left to right for the loading platform to deploy properly. Apologies in advance for the event of the platform refusing to retract all the way, as I tried my best while building to prevent it yet it still happens. There is also a battery and a diesel tank underneath the car bay for if you want to refuel or recharge your cars, but you can only do it while the cars are outside beside the train car and it is stopped.
