train not stoping when bridge is up

SwitchTrainTrack(0, true) -- Setting the Main train track(s) around LS and towards Sandy Shores active
SwitchTrainTrack(3, true) -- Setting the Metro tracks active
SetTrainTrackSpawnFrequency(0, 120000) -- The Train spawn frequency set for the game engine
SetTrainTrackSpawnFrequency(3, 120000) -- The Metro spawn frequency set for the game engine
SetRandomTrains(true) -- Telling the game we want to use randomly spawned trains

idk if there is a way to stop trains, and i dont think trains function the same way as traffic. so idk if id be able to make a function to stop train.

Here's an idea. I would try it myself but I am occupied at the moment with other tasks.

A train is an entity, and more specifically a vehicle entity, so it will be registered in the entity pool if it exists.

local vehiclePool = GetGamePool('CVehicle')
for i = 1, #vehiclePool do
    if GetVehicleClass(i) == 21 then
       --Check to see if it is on the proper track (Not sure which node your drawbridge is on so you'll need to identify if it is 0 or 3)
       if GetTrainCurrentTrackNode(i) == YOURTRAINNODE then
           --Do a distance check here to see if you should freeze it
           --If its far away don't worry about it (Depending on how long the bridges stay up for)
           --Maybe create a new thread if you find a train to periodically track its location in case it gets close. Just make sure to build logic to kill the loop once the drawbridge goes down
