How many of these examples are 34 miles in length or greater?
Philadelphia's trolley lines are each about 1/10 as long as the River Line which means they are easier to implement catenary and maintain.
Not all of the river line is street running for gods sake. I'd say about <10% of the line runs along the street. Yes, there are grade crossings but there were plenty of grade crossings on the 100+ miles on the electrified Virginian, N&W, Milwaukee Road, and Great Northern networks.
I honestly dont think costs due to extensive catenary maintenance has anything to do with this line not being electrified. It's because of the (A) Start Up Costs of getting wire there in the first place and (B) Do you know how long the pantograph would have to be expanded to reach Catenary at a sufficient height for Conrail trains to pass.
Yes, Double Stack trains do share electrified trackage in West Trenton, but Septa Silverliners are far taller than the LRVs that would be using this wire.
