Steam Can't Finish A Class 170 Service In Birmingham

I just got the class 170 pack and i'm enjoying it, there is a huge problem though. I can't finish any northbound service at all as it just gets stuck on lock doors even though I closed my doors. I've tried waiting untill my actual arrival time is and it still doesn't finish my run. There is no problem with southbound services but only northbound.

 

It does that on other routes you sometimes have to wait about 10mins after actually arrival time.
