This is a possible concise summary of the text:
The text is a transcript of a video about distributed power (DP) in railroading, which is the use of remote-controlled locomotives in the middle or end of a train to improve train handling, fuel economy and rail wear. The narrator explains the benefits and challenges of DP and shows examples of trains using DP or not using DP on different routes and locations. He also shares his experiences of railfanning, eating seafood and barbecue, and learning about the history and geography of the rail lines. The text is informative, enthusiastic and detailed about railroading and DP.
Here are the key facts extracted from the text:
1. Distributed Power (DP) is a technology that allows trains to be powered by multiple locomotives, which can be spread out along the length of the train.
2. DP is different from traditional multiple-unit (MU) lash-ups, where multiple locomotives are connected together at the front and back.
3. DP locomotives can be controlled remotely using radio signals, allowing them to be placed in the middle or at the end of a train.
4. DP helps to reduce slack action in trains, which can cause stress on couplers and lead to train separations.
5. DP can also help to improve fuel economy and reduce wear on rails by reducing the drag factor in curves.
6. DP units can be set up to mimic the commands of the lead engine, using software to account for the tonnage and length of the cars in front of and behind them.
7. DP can be used to improve train handling, particularly in hilly or mountainous terrain.
8. CSX uses DP to run longer trains, up to 15,000 feet in length, with some trains averaging 10-12,000 feet.
9. Norfolk Southern (NS) does not typically use DP on its trains, instead using traditional MU lash-ups.
10. NS trains often have a mix of different car types throughout the train, whereas CSX tends to group similar car types together.
11. K-423, an ethanol train, uses a BNSF C44-9W and a Kansas City Southern ES44DC as remote DP units.
12. Q452, a mixed freight train, uses a second engine as a DP unit, with 204 cars behind it.
13. The Howard Street Tunnel in Baltimore is too low for double-stacked containers, but work is underway to raise the tunnel.
14. The Port of Baltimore is eager to have intermodal trains serve its docks.
15. CSX has consolidated jobs through the use of cameras and remote control, allowing for more efficient operation of trains.
16. The Trout River Drawbridge is controlled remotely by a bridge tender located some miles away.
17. NS-330 was delayed for almost an hour, despite being on a double-track territory, due to unknown factors.
18. K-423 and K-811 were combined into one train, using DP to mitigate slack action and improve starts and stops.
19. The Canadian Pacific and Illinois Central railroads are involved in the ethanol train operation.
20. The train was able to travel a long distance with remote DP units, thanks to improved diversity and multi-frequency radios.
