Chaz said:The reason been is that the Pendolino has folding steps on the side of the train. Before the Door opens the steps have to fold out and after the guard pushs the "Doors Closed" button all the steps have to fold back in. I witnessed on a few occasions these steps can get stuck and have to have a little help from the Train Staff.
Folding steps aren't on the Voyagers as they are made by Bombardier.
Hope this helps you Jim.
