[PRCo] Motor flashovers on PCC cars

[Fred Schneider]

Does it not strike someone beside me as strange that MTA / MBTA had  
to downgrade the PCCs in Boston to 25 mph to prevent motor   
flashovers and the French run passenger trains every day of the week  
at 160 mph and just set a new world's record of 574.8 kilometers /  
hour (359.25 mph)?  It's enough to make a grown man cry.

I know Phil said 35 mph in his letter.  However, the motor speed  
charts for PCCs show that field shunting begins at 25 mph and field  
shunting was removed from the Boston cars.   I think Boris will agree  
with me that the now top out at 25 mph (40 km/h) on zero resistance.
