This has been an interesting discussion concerning the speed - or lack
thereof - of the 42S and 42L cars through Beechview. Particularly when
compared with other cities, the "swiftness" of PAT's light rail operation is
not impressive.
For what its' worth, much of what exists in the South Hills today is a
legacy of the Skybus controversy some 25-30 years ago.
q. Why does the light rail line follow the alignment through
Beechview-Castle Shannon-South Hills Village?
a. That's the Skybus alignment.
q. Why is there a Mt. Lebanon tunnel?
a. In large measure, probably because Skybus called for a Mt. Lebanon
tunnel. (and it makes sense)
q. Why is there no Beechview tunnel, and thus slow operation on Broadway?
a. Besides being frightfully expensive, I suspect that, since Skybus called
for an elevated structure on the hillside west of Broadway, surface
operation on Broadway was a way to keep estimated light rail project costs
close to the Skybus projected costs. (Just a guess - need to ask someone
involved in the decision process. Incidentally, Skybus would have continued
north from Broadway in subway towards the Wabash tunnel, then turn right at
the north end of the Wabash tunnel to follow the PRR towards the Panhandle
bridge)
q. Why was the Penn Station spur built in the Golden Triangle?
a. That's the Skybus city terminal.
The discussion about Broadway operation in Beechview leads to speculation
about the following:
- So what exactly is a "light rail" line???
- And how is it different from a "streetcar" line??? Or a "tram" or
"trolley" line???
- Is it the vehicle or the right-of-way - or both that define a light rail
line??? Or something else???
- Have you considered that the Duewag U-2 car is not a light rail vehicle?
It's a "Stadtbahn" (or city railway) car from Frankfurt, (W.) Germany. (And
therein might lie some of the problems with Broadway.)
There's a story that Ed Tennyson (Deputy Sec. at PennDOT during 1970s) likes
to tell. Gov. Shapp once asked him "what is this 'light rail' thing?" Ed
asked the governor if he had ever used the Shaker Heights line when he went
to college in Cleveland? When Gov. Shapp said "Yes, and it was good
transportation", Ed replied, "well, that's what light rail is!"
And maybe that's what the 42S line through Beechview - isn't. It's still a
streetcar line (operating in mixed traffic), and will always be one. It's
just not worth the cost to upgrade to eliminate mixed traffic. And it would
also be less accessible to local residents. Instead, perhaps Pittsburgh has
always had a light rail alignment through Overbrook. And what PAT does with
it remains to be seen.
Just some random thoughts.
