[Solved] Need a pulse signal when the train leave the statio

[DOSorDIE]

Need a 1 tick long signal when the train leave the station
I read that train id and make to T=1
And when that change to T=0 (when he leave the staion) than i need that tick.
How do i make that?

When T=23 and change to T=0 (or something different) then send 1 Tick A=1
but NOT when T=0 change to T=23 (or something different)

EDIT:
I trigger it with if T=0 then T=1 when he leave the train station and it work perfect
