Re: Birney 62 Tours San Francisco

 

You'd think from an FRA/PUC point of view that the Birney's wheels would have to be
turned on a lathe and returned to the? proper profile? or else
the wheels replaced to be in compliance? .? Having chipped wheels is asking for a broken wheel
and a possible? derailment .? Things can get really ugly really fast with a broken wheel.
I don't know if MUNI is part of the AAR but on the freight railroads , the rules are very strict
about wheels and since the physics is identical, I would think they would have to comply with
AAR standards/Cal State PUC? rules .? I've personally discovered? a chunk missing out of a wheel
on a loaded boxcar and we walked? it ( walking? speed and walking right beside the wheel)? up the
Penoyer siding and set it out on the house track.? They later came out when the wheel truck and crane and replaced the entire axle & wheel set.

Daniel,

I've heard this is true. SN 62 had deeper flanges than the Muni Streetcars, and the car ran more on the flanges than on its wheel treads in the Muni's shallow girder rail. The result was that the Birney's flanges were badly chipped.

Does anyone know if the damage was ever repaired and how, or if the car is still running with the chips?

Yours Aye,


Garth Groff ??

These are great. Thank you. I heard that this tour damaged the wheels of 62. Is that right?
