   True.  However, the CPR rulebook I found online didn't make any   
   distinction between operating in the summer, winter, spring, fall - the   
   automatic brakes are supposed to be released when leaving the train.  I   
   was trying to come up with ideas why the rule might have been written   
   that way, rather than saying why it might have been a good or bad idea   
   to apply the brakes in this particular case.
