    Agreed! The PRR's electrification was truly extensive and extraordinary. The map below shows it in all of its glory, including the freight cutoff between Trenton and Harrisburg, the "Port Road" between Harrisburg and Perryville, MD and the massive freight bypass between Parkersburg and Harrisburg crossing over the Susquehanna south of Wago Jct.. So sad to see so many lines on this map shorn of wire.

    Another thing to think about, the Pacific Electric didn't electrify freight only lines, even when they connected to electric lines.

    In the 1950's, the PE leased diesel locomotives, and ran them under the wires. As soon as passenger service was discontinued, they pulled down the lines.

    Interesting detail on the PE bremner. Your post recalled a local road in my region, the Piedmont & Northern, The Great Electrified System Of The South. The P&N operated two disconnected segments in NC and SC totaling near 130 Miles, both built to steam road standards and electrified with 1500 VDC. P&N dropped passenger service in '51 and took the wire down a few years later. With the textile industry in decline, it was acquired by the SCL in '69. A few short line segments still remain, along with a number of its tile-roofed depots.

    The advantage of electric in the early days was higher availability and high power for mountain climbing. It all comes around again and the advantage of electric is in high power again - 8000HP from an 80 tonne 4-axle unit that does not need refuelling makes high power and high speed (rather than mountain climbing) possible with electric that otherwise would require a big consist of diesels.

    The power transmission costs of high voltage AC are not huge - but the cost of stringing up the wire and the more expensive electric locos is a big investment that modern railroads are loathe to make unless they have a rock solid business case and see a return on the investment quick enough to please the shareholders. I like to think that we might soon see a busy chunk of the UP electrified to meet increasing demand - an electrified railroad can make much better use of the track with tighter headways and faster trains, especially when the cost of carrying around the extra power required for a fast getaway or a steep climb is not the same as hooking on an extra pair of centennials!

    Also, electrics were far better in temperature extremes such as winter. Unlike steam, they did not lose power as temperatures fell. In fact, the free natural cooling actually helped.

    Except when the fine snow went through the carbody filters and shorted out the motors on the GG1's one winter!

    Thanks for the link Rick. Karl Zimmerman's The Remarkable GG-1 (c. 1977) has an accounting of this event from 1958. The snow was of such a fine nature that it permeated the G's French-linen filters and it crippled nearly the entire roster of Gs. At the peak, the PRR was able to field only a third of its New York/Philly trains. The P5's air intakes were higher, so didn't suffer from the malady and these were deployed throughout the territory to pull the Gs which kept their steam generators running to heat the trains. The PRR also brought in as many diesels as it could muster to assist.

    The GG-1's underwent air intake modifications which were successful, but their design brought a touch of dismay to purists who valued the GG-1's traditional appearance. [Photo is not mine, photographer not identified]

    Ah. So this event is why that feature is seen..... (y)

    I recently saw this article in the NYT on the Hydro Electric power in the PNW
    One has to wonder which of these were Milwaukee or Great Northern

    The answer is possibly one. That map needs to be labeled.

    I believe the MILW had two in Montana. One near Great Falls, the other, if I recall correctly near Thompson Falls. Both were sold off to a private owner. Only the latter might show on that map. They had none in Washington- They bought their electricity the entire time.

    The GN had one. It was west-northwest of Wenatchee, on that namesake river. Long since abandoned.

    Funny how that page starts out talking of going down river, but it sure looks to be going upstream.
