Is the NHSL the same track gauge as the MFL?
Would a NHSL car fit in the subway tunnel if it could travel on the same tracks east of 69th Street?
They both run on third rail, yes?
What would be needed for a one-seat ride from King of Prussia to center city on the NHSL?
Given the lines' proximity, those are questions that a lot of people wonder about. Unfortunately the answers are (1) No, (2) No, (3) Yes ... but, and (4) a LOT:
(1) The MFL uses the (in)famous Pennsylvania Trolley Gauge of 5' 2½" while the NHSL/P&W is standard gauge. That six-inch difference is intentionally small, to prevent the use of mixed gauge.
(2) The NHSL cars are wider, which would preclude interoperability even if the gauges were the same
(3) Both use third rail but NHSL's is over-running and MFL is under-running.
(4) (1) to (3) mean the only option for a one-seat ride would be to do a significant rebuild of one line or the other.
Widening the P&W to trolley gauge wouldn't make much long-term sense because it would prevent future connections to any other standard-gauge line. Six-car MFL trains couldn't use the P&W ROW because of curves, station sizes, etc. Together those constraints would push towards rebuilding the MFL to accept P&W cars rather than the other way around, but regardless the cost and service disruptions would make a rebuild prohibitive.
If anything
were to be done to provide service east of Upper Darby, IMO it would involve separate construction parallel to the MFL. One option, proposed many years ago, would be to extend PATCO west of 15th Street to somewhere in West Philadelphia where it could connect to the P&W. A lot of PATCO's design was based on the P&W so interoperability would be far less of an issue. But right now even the much-discussed idea of extending PATCO to University City has become moribund. Without lots of money, lots of political will, and a demonstrable need, I doubt we'll see any eastern connections to the P&W before mid-century ... if then
