    Late BR steam period. Like building kits, and having recently got back into the hobby, enjoying it enormously. Built an 0 gauge DJH/Piercy B1 as my first 0 gauge project and now hooked on 7mm. So hooked that I persuaded SWMBO that we should buy Gladiator! Also offering a kit building service now. Finished working for Bombardier but doing some safety assessment work until the mortgage is paid!

  1. The video of Sweet Pea on the Middleton brings back happy memories. The loco was owned by the Leeds University Railway Society and used as the main motive power when students were running the goods traffic in the 1970's. Getting it to start on a cold winter day could be a nightmare. It required two people: one on the starting handle (yes, it really is a hand cranked start) and one on the decompressors. Plenty of easy start in the air intake and if that didn't work a paraffin soaked rag set alight instead. When the crankman had built up enough momentum there would be a huge shout and the decomp
  2. For the reasons that Simon has outlined I think it unlikely that Crossrail would be thinking about abandoning CBTC for the central section at this time. However, some observations: CBTC is (was?) only allowed in the central section under a derogation from the European Commission; the derogation requires that there is a migration path to ETCS, so it is possible that this has been factored in to the design of the ETCS sections. Reasons for allowing CBTC included headway requirements (now achieved with Thameslink ETCS) and PSD interfacing (achieved on Bangkok Skytrain, which isn't an ET
  3. At the risk of becoming too political, why not? Publicly listed private companies are owned by shareholders, such as pension funds and insurance companies, who invest in order to get a return. No business is going to survive if it doesn't make money. So the question is: can private companies offer anything that government owned ones cannot? I suspect that the answer in the case of a management contract micromanaged by DfT the answer may well be no. Whatever is put in place is likely to be a short term measure.
  4. Don't forget that lead is poisonous, so I would not run the risk, however small, of contaminating the oven with lead and infusing it into the Sunday roast, or pizza or whatever floats your culinary boat.
  5. True, but many more recent kits allow for a floating centre axle, which is a better solution. The only other point of course is to ensure that the axle bearings are at the same spacings as the coupling rods.
  6. A bit late to comment now but you can use a gas ring or cooks blowtorch safely to disassemble a poorly built nickel silver or brass model. 'Normal' solder melts at about 186 degrees, far below the temperature when brass glows red (650 - 750 degrees). Obviously not suitable for whitemetal!!! Once apart the desoldering wick is useful for cleaning up. You do need to ensure that the chassis rolls freely without the rods on and that all wheels touch the ground at the same time and the axles are parallel to each other. Your jig will assist in that. I would also strongly reco
  7. Thanks for these: very interesting. I was amazed how easy it was to get a possession in 1952!
  8. Horolene, but unless you want to varnish a brass finish there is no need to clean.
  9. As Edwin said, more precisely, small bore tunnels. I worked on the Taiwan High Speed Rail project which was designed to UIC infrastructure standards. The Japanese pointed out that a huge amount of money could be saved by adopting Japanese standards for tunnel sizes. (It was a potential saving of billions). However, the UIC sizes prevailed which meant that the Taiwan series 700 Shinkansen trains have a much more attractive front end than the standard duckbill ,which is essential to reduce pressure pulses and stop sonic booms.
  10. I don’t want to get dragged into details of Guild finances. The two big costs, publications and shows have a more detailed breakdown, certainly for 2019. Only Telford makes a loss. Telford also bears the cost of the AGM.
  11. Just for comparison. My wife and I run Railway City Trains Ltd, which trades as Gladiator Model kits. We provide a large range of 7mm loco, coach and wagon kits plus various accessories. Our financial year ends 31st August. Our accounts will generally appear in the Companies House pages about March. (we were early this year: February, but still 6 months). It really does take than long to get all of the books completed, reviewed by the accountants, prepared for filing and filed. Gladiator's published accounts do not show a Profit and Loss statement, but if they did then most things
  12. Agreed: the benefit isn't great but it is there, particularly in recovery from perturbations. Given the overcrowded nature of UK rail, these happen frequently. Yes, you can do the same in a fixed or virtual block system, but moving block is less hardware intensive compared with a traditional system with close signal spacing and these days probably cheaper (in metro applications at least) than fixed block: hence the move to moving block in most new metros. Train integrity detection is still a bit problematic for main line applications although Bombardier did manage it for its ETCS level 3 look
  13. ETCS level 2 isn’t that much different to a traditional fixed block system. You simply need enough free blocks between you and the preceding train to give a safe braking distance (with margins). If you kept the standard 1020m block length then just adding an extra block between trains gives you the margin required to run at 140 rather than 125. (Simplified but close enough). Essentially what BR did with flashing greens on ECML. The software won’t be any more complicated. The mixture of train types will be the killer for higher speed. Level 3 (moving block) offers benefits here.
  14. Given that HST’s managed 140 often enough before limiters were used, it ought to be a doddle for the replacement.
