So cool, but incredibly sad to see some of the catenary poles for electrification still standing, reminding us of what could have been

The MBTA’s refusal to install catenary (or even run EMUs underneath the existing NEC catenary) is so bizarre

US railroads hate catenary because they hate wayside maintenance, open and shut, that’s the whole story
NCTD's CEO defends hydrogen trains and claims that catenary:
- has same fuel cost issues as H2 (fact check: green H2 uses 3x more energy; NCTD's H2 prices went up 160% recently)
- is unsafe in fire zones (H2 is more explosive than fossil gas)
- has visual impacts

The world's busiest waterway is starting to get electrified. Testing started on a battery fully electric on a 10,000-ton 740-TEU container ship on the Yangtze River. The ship will be used for China's inland waterway and coastal shipping routes.

I'm pretty convinced that M8s have higher performance when running on catenary vs third rail.

A while ago @ultraviolet.gay was telling me about the former Pennsylvania Railroad Power Director’s Office at Harrisburg, which somehow in my travels I had never been to.
Well, now I have.

Catenary is MUCH easier to model, manufacturers like Marklin/Trix and Sommerfeldt make nearly ready to run systems you can use that are electrically functional.
Nobody's attempted this with trolley wire bc it takes serious effort w/guy wires, insulators & tension
