there definitely is, but the roads aren't going to share it.
and tracking trains ain't like tracking planes, where they're easy to see up in the sky and constantly transmitting -- train X takes a turn around a mountain and it's in a radio/cell deadzone and that's it.
plus unless you have high-end SAMs you're not able to impact most planes overhead, but shady individuals could certainly impact trains.
Train tracking in dead zones has approximately zero consumer-facing utility. Train tracking in urban areas would be very helpful for route mapping around grade crossings.
