Bogeys can be one of the hardest things to make due to having animation and a lack of good planes. There are a lot of tutorials on animation out there so I well be doing how real bogeys work part by part.
I well brake bogeys into freight, passenger, and powered. Trainz bogeys can also be things without wheels.
Real bogeys have to support the body and load weight, hold the wheels to the rail, and hold the brakes in place. A simple 4 wheel bogey can have over 20 parts all from deferent makers.
