  1. I suspect it's often cheaper and less hassle for the TOC simply to run buses and send the bill to Network Rail. This may be changing though - witness the thread somewhere else on here with 67s dragging 225 formations diverted off the Leeds route.
  2. Not sure about that. Gerry Fiennes made the point that a lot of routes went straight from fully staffed and presumably fully signalled to complete closure during the Beeching era. I think rationalisation to sidings, along with bus shelter stations etc, was more of a 70s thing by which time almost all the routes that were going to close had already gone. The explanation may be to do with freight. Quite a few stations etc that closed to passengers before the Beeching era retained their goods services and I think the idea that local freight was dying hadn't really registered with British
  3. Not familiar with these models but if there is a PCB it is possibly damage to one of the components on it.
  4. To answer the second one first, you are right the frame would control the access crossover and would be released by the signalbox. It would have to be restored to normal with the points normal before a train could be signalled into the loop. The ground frame would not control signals, unless the sight lines were too poor for hand signalling to be used. The frame is either two (in this case I think) levers or a small panel. It is located where the shunter can see the points and give hand signals to drivers, and is normally open to the elements. The other points would be hand worked by leve
  5. Looking at the scale plan in the original post, I think the signalling plan is a bit misleading in its proportions and these signals are in fact OK.
  6. As usual it's best to state your era and region, and it would also be good to know how busy the main line is.
  7. This is my suggestion (2) above. I contend it is not necessary with Peco code 55 unless anyone can say from personal experience with this type of trackwork that they have had a problem with shorts between the switch blade and the stock rail. The advice about a light bulb is also controversial and has been argued over on this forum many times. I don't intend to get involved in that discussion, but if you independently wire the frog then the problem mentioned with "hot spots" shouldn't arise.
  8. Yes I've no doubt they work as advertised. The problem is that they are expecting you to isolate the frog completely if you plan to use them for frog switching.
  9. Sounds like the explanation I posted. The Heathcote device will energise or de-energise its relays immediately the point is commanded to move, and almost certainly the relays will switch faster before the point motor can move the blade away from the stock rail. Result: short circuit, sometimes but not always depending how good the blade contact is. You could perhaps try to slug the Heathcote device with capacitors so it operates more slowly, but I think this would be a lot of hassle to get right (if it is too slow you will have exactly the same problem) and might go wrong again if the
  10. Didn't Charles and Diana travel in this one on their way to honeymoon at Broadlands? That may give some alternative search terms when Googling for pictures...
  11. No signals around St Keyne. There is a token for the section between Liskeard and Coombe and a one-train staff for Coombe to Looe. Coombe Junction is operated by the crew using a ground frame so no signals there. Don't recall if there are any on the branch at Liskeard.
  12. The new toolings launched since 2006 or so are almost all excellent - these cover all the main diesel classes but steam is a mixture of new models with some of the old clunkers on shopping trolley bogies still on sale. To me, N gauge allows trains of reasonable length to run in a landscape and is a good scale for people who like operating a railway. The new toolings allow this to happen without always noticing horrible errors in the trains. The only think you can't really do is on-board sound, though even that is possible with some models. On the other hand the size and relative
  13. This one comes up fairly regularly. There are two modifications you might want to do: (1) Connect the frog to a switch which changes with the point, so you are not relying on the contact between the blade and the stock rail to power the frog. This is a good idea as this contact often fails especially if the rails are painted. (2) Isolate the blades from the frog area (eg with a slitting disc) and bond them to the stock rails. This avoids short circuits if the backs of wheels touch the blades. If you do (2) you have to do (1) as well otherwise the frog would always be dead.
  14. True, but they were quite common in the OP's area and period - I travelled daily from Fife to school in Edinburgh between 1978 and 1980 so I was pretty familiar with the resignalling. I don't remember seeing any outside Scotland though. Re the signal diagram the loop exit signals should be three or four aspect not two aspect. I'd also stick with three aspects on the main line, as far as I recall there were no four-aspects in Fife.
  15. This site, intended for cyclists, allows you to measure distances online based on aerial photography.
  16. You could have the main signal just before the points where the first loop converges and both the loop signals further back just before they converge with each other. That would probably be far enough apart to give you an excuse to approach-light the loop signals.
  17. I agree if the second loop is used to refuge trains passing through the area then it would almost certainly have an exit signal and also an appropriate route indicator on the signal that controls moves inwards. Normally the signals controlling the two loops would be alongside each other but if a long train in the first loop (nearer the main line) needs to stand over the exit points from the second loop then the signals couldn't be in line. In this case I think when a route was set out of the second loop then the first loop would have to be empty and both loop exit signals would show the
  18. You could certainly do this with a computer. Otherwise there are some hardware systems such as the Lenz ABC, but they only work with certain makes of decoder and the logic needed to switch them on and off is a bit tricky. On the whole this is a bit harder to to in DCC than in DC.

    Red Caboose couplers (formerly known as Unimates) seem to be pretty much unobtainable at the moment. Someone has suggested that Bachmann (USA) dummy knuckle couplers are also suitable for connecting rakes that stay coupled together in service, but I haven't tried these yet.
  20. If you look at Googlemaps you can see where the railways used to be before the bridges were built. They seem to have built the bridges alongside the railway then diverted the railway onto them. You can also see how they combined the Crewe and Chester lines south from Warrington onto a single bridge. I believe some of the bits of old railway were kept as links between the main line and the ship canal railway system.
  21. That seem as good a reason as any not to buy one, or an iPhone/Pod to use it on.
  22. As usual the answer is "it depends". The attached shows two sets of concrete sleeper track at Curriehill, identical traffic and speed just different direction of running. The nearer track is more recent and appears to be the product of one of the track replacement trains, and its sleepers are distinctly closer than on the other track. I had a straight down photo from the footbridge but unfortunately seem to have mislaid it - this pic doesn't show it so well but it is still evident if looked at closely.
  23. Even if my German was up to it I probably wouldn't understand this fully, but from the diagram it looks like if you just want the wireless interface you only connect the router. The PC looks like a separate device as if connected by a LI-USB, rather than something the instructions have to go through on the way from the wireless to the command station.
  24. Interesting, and good to see that the operator is getting the trains through under diesel power rather than just turfing everyone out onto buses. Were they diverted off normal route, if so where? Re the drunks, my sympathies are with the dogs.
