[PRCo] Re: Question about 69 Squirrel Hill Route

 Sounds odd to me as we are always trying to minimise the unsprung truck
weight -- up to the point where the truck is unstable or has wheel-lift that
could cause a derailment. Possibly this is why, a truck designed for slower
speeds on street track, needed better stability for higher speeds on "T"
railtrack. Lighter trucks mean less wheel and rail wear and slightly lower
power consumption.

Istill want someone to tell me how it was done rather than simply tell me
thetrucks were heavier. Phillip, where did you get this information that
weight was added to them? On May 4, 2012, at 3:37 PM, Derrick Brashear
