When running services in the MBTA F40PH the brake pipe pressure will decrease from 110 psi to 90 psi. This causes the train to come to a stop as the coaches are meant to have a brake pipe pressure of 110. I have tried multiple ways to fix this while in game including cutting the brakes in and out and setting the train brake to emergency. The only option on the brake cut off valve is in so I'm not sure what the problem is.
