I guess the other name would be catenary safety covers ! Those covers that stop people reaching down grabbing XXXX volts of electricity. This pic courtesy of Dapol... Cheers, Gary.
Think they're smoke deflectors Gary, remnant from the steam era. All the modern footbridges have solid sides for the reason you outline. This is the current Cheshunt footbridge that replaced the first one that had to be installed when OHLE was put in (link in previous post). https://www.google.co.uk/maps/@51.7027249,-0.0241317,3a,75y,65.23h,85.47t/data=!3m6!1e1!3m4!1sNp6R4zLTVSpxtdDsHElGhg!2e0!7i13312!8i6656 Ed
Having been playing around with a 1150mm x 150mm piece of MDF to simulate a sector plate, I’ve come to the conclusion that a 1220mm x 320mm version with six tracks and loaded with trains is just going to be too unwieldy. A traverser is probably the way to go in the long term, meanwhile I’ve widened part of the base board and with two left over point and odd bits of track I’m adding another two sidings to the storage area. Total cost = nothing! I’ve also put the next two sections of catenary up temporarily in the station. Not quite straight, but they will have to come down again and be tidied up when the platform lights arrive (currently in a container somewhere between here and China). There’s a slight sag in the wires in that the pantograph just touches the wires at the center of the span, whereas there’s a gap of a couple of millimeters elsewhere. Considering the system is not properly under tension, I can live with it and these are the longest spans anyway at 510mm. Ed
Looking impressive Ed, I admire the nerves of steel to take on the catenary. it will be brill once all in place. The extra storage never goes wrong either. cheers toto
Thanks Toto. I'm only trying to represent catenary not model it that accurately and it passes my three foot (plus two) rule Ed
Looks fine Ed. i don't think we have any authorities on it on here, and if we do, I can think of another rule that I could apply. The thing is, it gives a good general impression. keep up the good work Sir. toto and talking of good work ....... its just about time to hit the shed.
ed photographed : Really like these two pics Ed. Great work on the catenary. Will look fantastic when all is completed. Cheers, Gary.
I have some catenary from my previous Triang incarnation. I used it on an excuse of a layout I now refer to as 'the learning curve'. What I did was adapt some Hornby (from their international range) catenary posts to take the Triang wires.when running my steeple cab and E2, the Triang posts looked too heavy. This allowed me to run a s' cab and a loco at the same. time. The early Triang wires look too heavy as well so for future use I want to use the single wire type I collected long ago. Your set up like pretty good to me Ed Ian
It'll look better when I straighten the wires up Gary Thanks Ian. Think 'live' catenary with DCC is far too complicated as if the contact wire is one particular pole (either +ve or -ve) and you take a loco off the track and put it back the wrong way round................ it will short My representative styrene posts and portals are actually a bit flexible, so there is a small amount of tension being applied to the wire sections. So far, so good. Fingers crossed as I work my way back around the layout Ed
As I've been asking about powering a lift out baseboard section, I thought I'd post what I'm doing. The extra two storage sidings I am putting in are shown blue in the plan below. While working on them I realised there was enough space to extend the main loop along the side of the storage sidings, across the work table and then back to the main baseboard. Saves me having to keep raising and lowering the hinged section every time I need to get to the storage sidings, and gives me a lot more space in the middle which was getting a bit cramped. (Also gives the trains a slightly longer run.) This is where I'd got to last week. Ed
I think you'll notice a big difference in the running potential Ed. It looks really good. You've not wasted any time bringing in the changes. Very good Kind Sir, cheers Toto
Sorry Ed, I've awol for a few days, for the wiring, I'd connect the feeds from the hinge end, via a relay (DPST), controlled by a limit switch at the open end. Adjusted so that if the lift out section isn't firmly down, no power is applied to the lift out section, and the two adjacent sections to stop a train running through to the gap. Paul
Wow Ed, that is some major change and it looks good. Gormo has used micro switches on both the hinged end and open end of his hinged sections on Great Chesterford. If I remember correctly. the last 12" of track each side of the lift out section, is isolated as well. This will stop any locos from taking the leap of faith ! Cheers, Gary.
Thanks chaps. My isolated sections are actually a bit longer, at convenient track section joints. Spent all yesterday morning dismantling the old hinged section. Should have only taken an hour or so, but Osteoarthritis in my back keeps making me sit down. I've moved the bus spur that ran up the hinged section, so that it now runs along the left of the plan and under the work table. Also done some of the track alterations to get the loop to run down the side of the storage siding and on to the work table. The brass strip I've ordered has just been dispatched and should be here Monday, so might have a train running around the new loop by the middle of next week. Ed
So far so good Toto. I'd also replaced the Lima couplings with Kadee #19s, so it was a bit of a double test. No buffer locking or derailments................. and they just look so much better. Ed
