81F, Sorry I cannot answer the tare vs gross weight but I always thought there were 20 cwt to an imperial ton in which case subtracting 6t 17cwt from 16t would give 9t 3cwt.

Hi Aldebaran, You do really well posting in English but plaies is one of those words that confuses most people : it is spelt plays.

I rarely respond to the Hornby emails but do note that this is promoted as a "Pre Black Friday" so hopefully there will be a wider range of "bargains" on the 24th November.

Could the title please be amended to something a little less generic, maybe include the words level crossing packaging?

SOT, May I suggest changing the thread title to "Rewinding old X series motors"?

Peachy, this will overcome the drag of a 1.8% climb. In my plan I intend the outside loop on both to be the climbing lane, so can you recommend a radius? I can't recommend a radius but can give you the formula for you to calculate. 1.8% is 18mm per 1000mm run. Circumference of a circle is 2 x r x pi. Your helix will need to climb the headroom in each full circle, call this H. Thus in each full circle your helix will climb 2 x r x pi x 18/1000, where r is in millimeters. Pi is roughly 22/7 but the proper calculation will show the climb is r x 0.1131. Therefore H = r x 0.1131. Use this formula with whatever H you choose, for H = 75mm the radius is 663mm, that's your climbing lane.

I am not familiar with problems associated with joining Peco and Hornby track but would strongly advise against using anything other than flex track for a helix. The physical difference in diameters on a helix vs flat circle is very small but I was much happier using flexible track on a helix I built many years ago. If you are constructing the frame/support yourself, and no reason not to, then be careful with the gradient calculations [inner track if more than one] and ensure sufficient headroom under the support of the above track. Helixes need a fair footprint. You might also want to introduce a vertical transition on the entry and exit track(s).

Rob, Fascinating update re Ray's detection system and combined development. I have on occasion, like many others, voiced my frustration [and anger] at Hornby's failure to launch their loco-detection, or at least admit it isn't coming. Financial concerns have meant I have yet again postponed my full retirement and currently I wouldn't have time to do justice to trying Ray's system.

Pirlouit95, Not quite. If you round up to the nearest inch then 14' 7"5/8 becomes 14' 8". I am surprised that it is not rounded down to the nearest inch, which would then be 14' 7" and your example would be correct. 14' 8" minus 3" becomes 14' 5" and rounding to the nearest multiple of 3" results in 14' 6". Way too much thought for a picture/model of a simple bridge.

CORKY, You seem to have some knowledge of these matters but are you sure that 3" is added to the measurement [rounding up!] with another 3" added to give the clearance. My simple brain suggests tolerances would be deducted, otherwise there would be quite a few tall vehicles hitting the bridge!

Injury20, Some sort of Folly, or search Google for Wellington Monument and perhaps a smaller version! I have attached a photo of how I fixed grass matting hanging down along the edge of my township to try and hide the join, the tape measure is only there to show the gap! Perhaps a similar method could hide a horizontal joint.

RP, Can you not share your source, re "I have it on good authority"? Unlike some I certainly would like further development, including local detection (which was my main reason for buying RM many years ago!].

I haven't fitted a smoke generator but have read several posts about them and vaguely recall something about their current demand sometimes can be higher than that provided by the decoder function circuit.

Waste of my time clicking on this thread.

Bulleidboy, Yes, I saw that in the TV episode but didn't see any reason for the wrong wheel spacing; ColinB has suggested the Designer may have wanted to "carry over" the old designed chassis. I'll have to see if I can watch the episode again as I thought the Designer had mentioned a "compromise".
