Pilotmen do not have to stay with the same loco. The loco diagrams should change throughout the weekend with different combinations on Fri/Sun to Sat. 33053 will not just be a brake translator for the 56. The 56 will always run with one of the vac fitted locos for a brake translator on passenger services and so a mix of 56+33/37/73 is possible. However, it can run trains such as unfitted freight etc without the translator. Hopefully you will see the 33 running trips on its own and also with an ED. On the point with regards the length of days and the 12 hour discussion, one thing perhaps that people don't consider is that the staff who travel to work must also be fit to travel home at the end a shift - directors of any company cannot ignore this. Do not also forget the rest required between shifts for safety critical work. With all the will in the world of any volunteer, there are always rules to which they must work. For MHR, the commute could vary between 400 yards to 130 miles. Every railway has a different volunteer base and the size of pool of qualified staff will also vary. One size doesn't fit all but we can always grow and will always welcome new volunteers.
