Having a real pickle with this train and the wsr passenger service. Trains already running and I’ve fully applied and fully released the train and loco brake. When I’m applying throttle I can’t get this thing to go above 5mph. If I apply too much throttle the train stalls, if I get it up to 5mph slowly and then apply full throttle it bogs down. I’ve also tried holding brakes on release to see if system pressurises but it doesn’t seem to. I’ve tried disconnecting and reconnecting wagons, this also has not solved issue. In addition to this I have checked handbrake is released in the train and in the middle passenger wagon. I’m confused. Anyone able to help?
