  1. If we could turn round trains like the Japanese Shin-kansen does then Old Oak Common would have plenty of capacity, and the platforms proposed for Euston could be further reduced saving some real money instead of wasting money by postponement. IMHO the cost differences come from several things; the pandering to nimbyism, the constant changes from govt level, the building of palaces at either end (and having to many ends instead of through running) where Germany and France use mostly existing stations, the desire of consultants to constantly find new innovative ways to do things and having to keep writing new reports about the latest suggested changes.

    Dapol signals

    Those TT3 signals look nicely done but using RC Servos rather than solenoid point motors will make a much better job. Plenty of info on here in using Servos for signal operation. eg The series by Steve Hewitt.
  3. Well now, it was actually me who said that the OP would need to measure the rail. And Martin who appeared to suggest that that was not needed as it would be automatically rescaled, perhaps because of my post wrongly mentioning the chairs page rather than the rail page. But Martin has now explained the process for inputting a rail size in more detail when a rescaled rail won't come out right. We all owe Martin a lot for providing us with the fruits of his hobby so we can use it in ours, and his explanations and documentation is so exemplary it comes as a bit of a surprise if something is not clear.
  4. Well now, maybe that could be mentioned somewhere on the relevant page. I was just reporting what I saw on the rail page after my Templot updated yesterday, a selection of 4mm and 7mm rail sections and a box to input your own. No mention of what would happen in other scales. In this case the OP wanting to model in 1:120 but being stuck with an oversize rail (code 60), how is he to get the chairs to fit?
  5. The code 60 is about 7% oversize for TT3 and 20% oversize for TT120, code 40 is of course undersize approx 15%. You are going to need to decide your personal compromise. Templot 3D printing has predefined chairs for 4mm and 7mm but you can input details for any other size, you will need to be able to measure the rail accurately.
  6. Note the Peco track is meant to be flat bottom so would not be code 48 anyway. But the rail they have used is the same rail as used for their N gauge and is really code 80 with a double foot so the bottom 25 thou is embedded in the sleepers leaving the top 55 thou looking like normal flat bottom rail, not really suitable for DIY track.
  7. Since 1:120 is a brand new scale for british modelling and so far is effectively RTR only and none of the makers are producing track with scale rails let alone bullhead you are going to have to compromise. The established scales for british buildrs are 2mm to the foot and 3mm to the foot. 1:120 sits in between so available rail will be either to small or to big. As an example here are the dimensions of BS95R bullhead rails. Prototype, 2mm(1:152), TT(1:120), TT3(1:101.6) inch, mm, code, mm, code, mm, code, mm Rail height, 5.7, 145, 38, 0.95, 48, 1.21, 56, 1.43 Head width, 2.75, 70, 18, 0.46, 23, 0.58, 27, 0.69 NB. Code = thousandth of an inch.
  8. In the case in question the loco was not exactly 'propelling' the report makes clear that the driver just released the brakes and had no need to open the throttle as gravity moved the train. The shunter was controlling the brakes from his end and had the train sliding before the impact.
  9. Quite an eye opening report on the complexities of operating a busy terminal with antiquated signalling.
  10. Euston must be the worst case of a bank off the platform end, enough that it was originally provided with cable haulage. But at one of the rebuilds the backing out roads were provided so that the coaches could be reversed into the platforms by the train engine so there would not be a loco in there to do any banking. Refer http://www.norgrove.me.uk/signalling/plans/Euston-a.gif
  11. Generally there are two main options, 1. Make the joint on the centre crankpin with each rod half thickness at the crankpin, make the protoype joint just cosmetic. 2. Make the joint where the prototype does. a. If using two layer rods make a half joint as 1 above fixed with a pin soldered to the rear half or riveted. b. If using 3 layer rods solder a pin to the centre layer then fit front and back layers round it and solder the layers together. Either 1 or 2 will work, experienced modellers tend to prefer 2. 2b makes a very nice joint if you can get appropriate etched rods. Etched rods can be had from Alan Gibson, Bill Bedford, Lanarkshire Models and Supplies and no doubt others.
  12. And what was the problem with the other locos that derailed? Your first post said some of your locos and the loco pictured was said to be one of those.
  13. Also the same enlargement shows that the alignment of tracks where the curved rail joins to the point is poor, showing a distinct gap in the plastic base on the black wire side. This will cause the wheel flanges to run to that side approaching the point and thus more likely to catch on the switch rail Andy refers to. You need to fix both problems.
  14. The GC had a pumping station and tank just east of Guide Bridge taking water from the Peak Forest canal where the line crossed it. Beautifully kept pump etc when I visited during my railway training in 1959/60.
  15. From what has been said the unreliability has more to do with the drivers, and given how long they have had these sets a lack of trained drivers would seem to indicate a management failure. Equally given how long they have been in service there should surely be a liability on the manufacturers and lessors which TPE should be managing.
  16. Given the very variable conversion factors betwen the imperial and metric columns in that table one wonders what tolerances they worked to and which column was used in manufacture?. Which column of dimensions did your wheels 'exactly' match? It can't be both.
  17. Given in detail in Kevin's link, D for Defibrillator.
  18. Doesn't look like many people read that request. 😒
  19. There seems to be a bit of confusion between filament buld and LED in the question. Traditional banner repeaters were originally lit by oil lamps with the lamp externally at the back so the actual banner had glass both sides. These could be converted to filament bulbs and would not look any different. But banner signals designed for electric lamps would be glass on the front only and had a dome shaped housing at the rear for the lamp and optics. Usage of these would be dependent on the availability of power supplies but would have been used with colour lights as power would be available. Not sure of dates but I would think from sometime in the 1920s/30s. So definately what you would ecpect in the 70s.
  20. In the 70s I'm pretty sure they would have been real banner repeaters, the LED version possibly late 90s. Ones with green LEDs not till this century.
  21. The original suggestion here was for brand new development above the new Euston. So problems with converting redundant offices are irrelevant. Whether anyone could invest in such for 50 years of rent is the more relevant issue. I would doubt that they could be built as "affordable", perhaps very high end?
