I'm not sure what to make of Thomas running a bit jerkily in reverse, but I think I have a solution. Run him forwards a bit too fast, for about two or three full laps. After the third lap, try gradually slowing him down and he should move more smoothly. Try him in reverse again, a bit too fast for two or three full laps. Repeat the process and he should move more smoothly in reverse. Joem is very handsome. I wouldn't be too surprised if he managed to haul a short goods train or something, on Sat. 6th July, which is only a few days away. I'm looking forward to my 42nd birthday.
