The Lackawanna had bad grades in the Scranton area.
The Erie had relatively easy grades by comparison -- Port Jervis to Otisville tunnel, and over Gulf Summit -- but that was about it.
If I remember correctly, the Erie gantleted the track over Starrucca for a number of years when they started buying large modern locomotives like the S-class Berks. Apparently it was determined that the viaduct could survive the live and impact loads of two power consists running in opposite directions, and the double track was restored.
I have never been able to look at a modern train on that viaduct and not become needlessly concerned that the tops of the arches are too thin to support the weight. They were, and are.
The sad story is that EL deprecated the excellent high-speed Lackawanna Cutoff and Tunkhannock/Nicholson Viaduct route in the early 1960s in favor of the double-tracked ex-Erie route. Perhaps associated with this, there used to be a long plate-girder trestle across I-80 close to Fairfield that disappeared at some point over the years. The effect was that the high-speed route around Garrett Mountain near Paterson was lost, and with it most of the point of keeping the Cutoff in service at all. Then under Conrail there was little perceived need for the Erie alternative itself, so it was single-tracked and then much of it abandoned as a through route...
When built by the Erie Railroad, the bridge was single track using the original 6-foot guage track. It was widened to two tracks in 1886 when the Erie converted to standard guage.

The last time I was over it on a freight train was 1988 (Conrail).
I'm thinking the second track was pulled up after Norfolk Southern took over.
Starucca as built was a double track viaduct. It was single tracked a few years ago long after Conrail was in existence.

I always get the Starucca Viaduct and the Tunkhannock Viaduct mixed-up, even though the Starucca was stone and the Tunkhannock concrete, but I believe that both were double tracked at one time.

Just watched a video on you tube about Starucca Viaduct. Beautiful stonework on a bridge that is 175 years old and as solid as the day it was finished. Since the existing track is off to one side was it built and had two tracks or was it designed for two tracks and the second track was never installed? Thank you
