PlayStation Keyboard Command For Train Brake Handle

Hi Guys, Hope someone can let me know what the key command is for the Train Brake Handle (31 on image below) ? I have tried all commands and can't put my finger on the right one.

 

; and ' to decrease and increase

keys right of L key

 

One of the brake keyboard commands doesn’t work on Playstation. The controller has to be used. It’s been like that for years.

 

Many thanks for that.
