I’m not quite sure if this was ever published to real paper and I’ve been looking through Abebooks.com and the like trying to find it. No luck so far.
I really enjoyed the section describing what it was like to plan the actual movement of GO’s trains through the already busy rail network around downtown Toronto and it was really neat to read about their scramble to find more rail cars when it turned out the service was actually more popular than they had predicted.
Anyway. Take a look.
