What's the background music that plays from 2:56 to 5:36?

if you spoke to PRR engineers who piloted the T1's the majority of them would say that the wheel slip problem was a myth. The final analysis of this piece of railroad lore was that the engineers were not used to so much instantly available power, and that was the true cause of the perceived wheel slip issue. But as noted, most of the engineers were of the opinion that once used to the available power, and how to manage it, the wheel slip issue was non existent. But rumors, myths and folklore are hard to dispel, especially among non railroad individuals and rail fans.

Regardless of how practical or impractical they were, they definitely looked fantastic

The S-1 still looks absolutely amazing. I wish it had been designed a bit better with its weight. And been preserved...

I love how the T1s look. They have a very modern appearance.

Discovered this channel only a while ago, definitely one of the best channels for American loco history.

In the words of high iron “sometimes static display is a fitting retirement”

I like your theory about the PRR's engineers pulling the T1 throttles too fast. The great mystery is the entire Q Class. The PRR was always a 50 MPH freight railroad, with much of its cargoes being open top coal hoppers. That fact is why the PRR rejected the N&W Class A 2-6-6-4 locomotives, which they tested when they were considering the C&O T-1 2-10-4. That's probably also why PRR did not try the Challenger types (4-6-6-4). So why build such complicated locomotives with 69 inch drivers as the Q's? Thanks for promoting the T1 5550 project!

I’m not a train nut like most of you on here, but damn these things are beautiful. Something about more wheels, just looks amazing

I’m from Darlington, England. The world’s first passenger locomotive was built about 100 meters from where I grew up! The new steam locomotives, Tornado and Prince of Wales were also built at the same location and now run on the main line between London and Edinburgh (and stopping at Darlington of course).

For every great aspect of the duplex, there’s always a drawback and that kinda why I like them. Especially the T1’s. I always figured the T1’s were a tad too powerful for what Pennsy crews were used to, and this basically confirmed that.

here's to the newest T1 to be built, and hope it can break the steam speed record in the process!

Once met someone involved in C&O’s testing of the T-1. He said (which has been backed up by other sources), that the C&O liked the T-1 except when they tried to test it in the New River Gorge. The results were that the T-1 couldn’t maintain much speed through the Gorge, the constant turns and grades were hard on the T-1. The biggest problem was that it was simply too long to make the turn at Hawk’s Nest going the right way (eastbound and westbound tacks are separated by the river from Sewell to Hawk’s Nest). So the T-1 and its train had to back all the way back to Sewell (about 10-15 miles), and then proceed west on the eastbound mainline so they could avoid the curve

love the shoutout to the T1 trust!
