Hello Have you ever put a Keep alive in a MTH Subway engine I have two sets need so help with that.

[@dashingdanstrains]

I'm not familiar with what a keep alive is, what does it do?

[@BroadwayNexp]

is the MTH PS32 5v stacker board all thats needed when fixing a subway car? i have a dead board so im looking to replace it. is the PS32 board the same as a PS3 board?
Thanks for any clarification

[@dashingdanstrains]

PS32 isnt the same as a diesel PS3 board, a PS32 board is just another name for a stacker board, the internals of the board are similar to PS3 though.
To replace a PS2 board you'll need:
-A PS32 5v stacker board (AE10000355V)
-A stacker heatsink (IC0000026)
-A 4 ohm speaker, for that you'll need to check the diameter of your current speaker and order the appropriate replacement, I am not 100% sure of what the R36 subway is, but the R21 is a 50mm speaker, I assume the R36 is probably the same but you should measure to make sure
You'll also need a TIU and a windows computer to flash the chain and sound files.
Good luck!!
