OnPlayerUpdate doesn't works inside train WAGON

[tucho0]

Describe the bug
I have a gamemode that when you get inside some vehicles as copilot ( ambulance seat >= 2, trains and others ) teleports you inside a interior. the thing is the code was working nice in SA-MP and OPEN.mp, the ambulance interior and others vehicles, but inside train WAGONS wasn't working, debuing what was going on I noticed that I can't even use the OnPlayerUpdate CallBack when I get in on a train wagon

To Reproduce
Steps to reproduce the behavior:

1. Create some train with wagons (538 model)
2. Pres G on some of the wagons and then you won't see OnPlayerUpdate working, GetPlayerVehicleID returns 0

Expected behavior
OnPlayerUpdate callback working, GetPlayerVehicleID returning the vehicle id so I can teleport players inside interiors

Screenshots and/or logs
