  1. I have always expected RM WEB to want to supply accurate information in order to get the very best modelling results. So I try to base all my posts on running the numbers supplied by others and checking their validity by the usual proven scientific means. Mostly just simple arithmetic suffices. However, quite often the results are not want some people with optimistic and/or exciting new ideas and unsubstantiated opinions want to hear. That doesn't mean the scientific results and conclusions are reversible by a popularity contest, no matter how irritating the real answers might be.
  2. Martin has the demonstrated authority from RM WEB to alter and/or delete others posts on RM WEB's behalf. I.e he is an authorized (and de facto) agent of RM WEB policy. The rail width measurement, if reasonable, is only cosmetic, like the sleeper dimensions are for the DOGA. It (they) have no other effect on the running aspects of the standard. Andy
  3. Because as in all tech drawings, laws, legal documents, Templot versions, etc. the latest date always supersedes the earlier version. Otherwise nothing could ever be repaired/improved. Andy
  4. It's pseudo science to say that two different numeric values are the same. Either RM WEB throws it's weight behind and publicly supports the EMGS standards, or publicly denies them. The EMGS deserves to know, so it can post it's own response or otherwise if necessary. Just quietly urging EMGS members to ignore their own Society dimensions is crossing a heck of a red line for a forum supported by the widely read BRM magazine A more useful position would be to ask the EMGS WHY it has more vee check running clearance that the dimensions Martin supports. We can
  5. This was part of the information sent to me by the EMGS just one year ago this month. I respect their authority on the matter. So Martin, please promptly delete your incorrect and unnecessary edit of my accurate post. And desist in future. Andy
  6. Central Valley curvable turnouts bases in the US have used that approach 100% successfully for US HO since the 1970's. The only requirement is that the correctly positioned rail fixings match the rail base width sufficiently accurately. Then using a pre-assembled crossing and pre-machined points, no gauges or paper templates are needed at all, even for Proto:scales. And the build time is usually between 30 minutes and 1 hour, even for novices. The preformed bases fix all the rail positions relative to the few centre line alignment points provided on the base. Track p
  7. Actually having the extended nose platform set to the depth to just carry DOGA fine wheel flange tips completely obviates any need for the extra skill and effort of hand hand building for 00-SF. Blunt nosed vees or not. I've made and shipped many thousands of so fitted blunt nosed vee crossings (88- safe frogs in USA) for almost the past 20 years, without a single user complaint or return. So I can vouch for that being both an effective and far simpler engineering solution for running mixed RTR and "Finescale" wheels. Apparently PECO are now using the same technique for their r
  8. A very worthwhile project and well executed by the look of it. I see you have included the platform projecting some distance in front of the crossing vee tip. Why is that? Andy
  9. It's not obvious, but it has a small trailing truck as well. So make that a 2-6-2 PT. Andy
  10. https://www.ksby.com/news/local-news/wwi-era-steam-engine-restored-in-arroyo-grande-to-mark-armistice-day This is a news item from my local area. I'm not sure where to post it but I'm certain there's interest in various sections of the forum. If the moderators wish to move it to a better place, that's fine by me. Andy
  11. The Mole The MOLE and MOLE II, best of both worlds. Andy
  12. I can run HO 4 wheel bogie vehicles reliably on 8 in radius, even with proto-scale wheels, provided the bogies can turn sufficiently without hitting under body obstructions. For 6 axle and greater vehicles and bogies, minimum radius is set both by the amount of sideways movement of the "Mid" axles of a multi-axle vehicle and the track gauge. Note that 0 SF and 00 SF folks have a dramatically greater min. radius running the same RTR 6 axle and greater vehicles due to gauge narrowing. You can partially avoid buffer and/or coupler lock on tight same d
  13. Acceleration and braking a pod full of 20 or so people up to and down from 400 mph in a very short time takes a lot of power, regardless of low friction and the force needed is generated within the sealed tube. All that kinetic energy is transferred to and from the pod with less than 100% efficiency. The difference is going to be a lot of heat with nowhere to go. Even radiation is going to be reflected back to some extent. Andy
  14. Regardless of all the other technology , social and financial issues, I've never seen a mention of how the pod gets rid of the heat generated by the waste transmission power. You can't cool a object by conduction or convection in a vacuum. No is there any possibility of forced air fan or fast motion cooling or normal air conditioning. So given the enormous work done over distance, how does the system not cook the passengers? Andy
  15. I'm not sure what you mean by a memory position motor. Any simple stall motor type will stay at its last position during power off and adopt the position of it's control switch (usually DPDT toggle) on power on. Most stall motors include frog contacts. No electronics required. Andy
