The train stops because of the code inside the AcPatrulla block.
If you want the train to move like it does in the BEL mission, change line 1562 of the MIS file to
.RAIL [ .P1 [ 5130 260 0 ] .P0 [ 730 4666 0 ] ]
then change the code block between the lines 1648 and1667 to
[
acPatrulla
[
.CARISMA 100
.PATRULLA [
[
.TIPORUTA JUMP
.RUTA [
[ .XYZ [ 5130 270 0 ] .ANGULO 135 ]
[ .XYZ [ 730 4666 0 ] .ANGULO 135 ]
]
.VEL 10
]
]
]
]
and finally remove the line .REACTIVIDADES DEMO
That's all.
