Reply to comment by AirtimeAficionado in A T line from Pittsburgh International Airport to the Allegheny County Airport by MWBartko

A small nitpick, but even the older Siemens units can do 65, and the newer CAF ones hit 70ish in testing the blue line before opening.

I agree all the other expenses will keep this from happening unless the city population booms and the airport becomes a major hub again, both of which I don’t see happening any time soon.

Yes, but I don’t know if they could do them regularly/ if they could reasonably achieve those speeds for a long period of time on any realistic track configuration. I think 45 is a more realistic top speed that we would see, especially considering the grade that they would need to cover on such a segment, but I could be misguided here

The re-done blue line was designed and built to allow for hitting their top speed, but a variety of crossing and signaling issues have kept that from coming to fruition. The red line, downtown, and north shore certainly not going to get anywhere near that for sure.

As with all infrastructure, getting the planning right is only half the battle, execution can just as easily make or break a project.
