RMweb Premium melmerby Posted September 13, 2018 RMweb Premium Share Posted September 13, 2018 Later UK EMUs have many motored cars in the formation but only one pantograph is normally used. The Class 390 (Pendolino) has 8 motored out of 11 and two pants only one of which is normally raised. The class 800s likewise have 5 out of 9 (or 3 out of 5) motored cars but only one pant is used at a time. Keith Link to post Share on other sites More sharing options...

jasond Posted September 20, 2018 Share Posted September 20, 2018 I was told that higher speed UK stuff only uses one overhead collector, preferably at the rear of the train, or a second collector might have to deal with wire still jiggling from its first encounter.

Jason Going OT from the street stuff. High voltage bus lines along the tops of passenger vehicles was a no-go in the UK for many years - that's the reason why the APT-P had the two power cars in the middle of the two half sets. The rear pan is normally used on a Pendolino to protect the front pan if there is a problem that should bring down the wires and potentially damage the pan. At least the train can continue if it is clear of the damaged section. However, when two (or more) EMUS are coupled, they each have to have their own pan up to provide power to their respective cars (unit) I guess the US examples - as some are single cars - have to have a pan per unit (when a unit can be a 1, 2, 3 car or whatever, formation) Multiple pans along high speed trains can cause huge ripple effects along the contact wire resulting in bad contact further down the train. (Yes, I know they do it with TGV and Shinkansen etc). Link to post Share on other sites More sharing options...

Prof Klyzlr Posted September 20, 2018 Share Posted September 20, 2018 Dear Shinkhansen fans, IIRC the pantograph surrounds were at-least inpart an attempt to tame wind noise thru the assembly at Speed...

It looks like it might be the inverted equivalent of an oleo leg. It was used on the Shinkansen 500 Series and Showa IS a manucturer of shock absorbers. It was supposed to be much quieter than a conventional pan but I don't know if anyone else has used the design since. Seeing it on a moving train, it and the fairing around it. reminded me of a submarine's conning tower. The odd downward curved extensions to each side of the contact head are probably to minimise vortexes, rather like the upturned wing tips of most modern jet airliners.

Grovenor Posted September 24, 2018 Share Posted September 24, 2018 The odd downward curved extensions to each side of the contact head are probably to minimise vortexes, Why odd? downward curved ends are pretty much standard for pantographs, primarily to ensure that the head stays under any converging or crossing contact wires.

Regds You're quite right Keith and I've amended my post from last night. It shows how much attention I've not been paying to the design of pans even though I see them most days, and looking at the horns on that photos of the Shinkansen 500's pan more closely they don't appear to be aerodynamic in shape though almost everything else is. The actual head though is definitely wing shaped with an apparent angle of attack and I've seen it referred to as a Wingraph (Wing + Pantograph) I can see how that upward force would improve contact with the wire at high speed but, like a conventional aircraft wing with a definite leading and trailing edge, would only work one way. All the videos I've found of the 500 series show a rather more conventional single arm pan, apparently the vertical column design proved too expensive, but they do incorporate a lot more aerodynamic, vortex reduction and noise reduction design than other pantographs. Perhaps if we'd paid more attention to JNR's work we wouldn't have ended up putting so much of HS2's route in tunnels and cuttings or behind noise barriers. Dr. Eiji Nakatsu, who ran the technical development department for Japan's Shinkansen trains is a keen birdwatcher and various aspects of this train in terms of aerodynamic efficiency and noise reduction were inspired by birds including its characteristic "Kingfisher" nose. I've not been able to find out as much as I'd like to about Dr. Nakatsu's work but there is more about his application of biomimicry here. http://labs.blogs.com/its_alive_in_the_lab/2017/02/the-return-of-dr-eiji-nakatsu-and-biomimicry.html Edited September 24, 2018 by Pacific231G 1 Link to post Share on other sites More sharing options...

The train is running down Central Avenue(a.k.a.- Zero or "0" Street) in Downtown Phoenix. I have been in Phoenix for about the last 36 hours. The reason why I am in this area is because I have a career as a professional truck driver. Yesterday, I had visited a model train store called "An Affair With Trains"(www.aawtrains.com) in the northern part of Phoenix and I went joy riding on the Valley Metro light rail. http://www.railpictures.net/photo/462069/ Wendell Idaho, USA 2 Link to post Share on other sites More sharing options...

I am trying to view on a computer without any sort of adblocker installed and it still insists I have an adblocker. It's rubbish.

Mike Boucher Posted October 16, 2018 Share Posted October 16, 2018 Does it count if the street is a bridge? (and a toll bridge, no less) Springfield Terminal railroad. a whopping 6 1/2 mile long railroad, at one point electrified, running from Charlestown, NH, to Springfield, VT. Eventually taken over by the Boston and Maine, and merged into Guilford. This photo, taken May 20th, 1975, shows eastbound GE 44 tonner crossing the bridge over the Connecticut River. Cars had to pay a toll, as the bridge was owned by the railroad (at least, that's my understanding). While the tracks are long gone, the bridge still stands, no longer a toll bridge, carrying cars only. 9 Link to post Share on other sites More sharing options...
