I saw video of this train on Shap, later learnt loco had failed at Carlisle. Just a question about the rolling stock: all Mk1's (hooray) except the last carriage Mk2 air-con (boo). Do I assume they don't have one MK1 TSO with door locking to complete the rake? Also how do they power the Aircon? Is it from the 47 on the rear?
