    Thanks - perfection - easy when you know where :D

    Even easier using the GOG Product Directory using the term 'holderbat' - the correct name for a pipe fastener.

    Thanks, but it's not self evident to me. I suspect the lighting obscures its function. Track gauge? Jewellery? Modern sculpture?

    41-S7 Sliding Track Tester - Large.jpg

    The block is c38mm x 63mm. There are two parallel raised strips remaining where the block has been milled away, one towards the top, one at the bottom. The dimension across the outer faces is the track gauge. The thickness of the raised strip is the flangeway width. You can use this for checking gauge and alignments though e.g. turnout common crossings.

     I do plan to do 31.5mm gauge, if I can locate some good track gauges for that size. The big saving grace of O gauge is that even though it is "out of scale" compared to a dead-scale track, it works out to an error of about 3%, which I can easily live with. 

    31.5mm gauge will give better running but at the cost of increasing the fudge factor to 4.5%!

    Don’t judge me!

    Ok then, I'll judge Dapol! This livery was carried by 1426 for only two years from its overhaul/repaint in Caerphilly works in Mar/Apr 60 until withdrawal in April 62. A very narrow window!

  5. Don't get too bogged down in the numbers. Rice's plan has platforms c4'6" long which would be nearly 8' in 7mm - almost twice the length of any train that your fiddle yard could deliver. I suggest that you avoid building a model of a model. Instead, look at a suitable prototype station that takes your fancy, assess its suitability to sustain interest and mock it up with printed paper templates on a piece of old wallpaper. You will have to compromise, reduce platform lengths etc but that's part of the fun!

    I'm going on to it shortly to find out when number plates became white/yellow with black letters as opposed to white on black!!

    Reflective numberplates were available from 1968 but became mandatory on new vehicles from 1st Jan 1973. Vehicles can, after application to the DVLA, use black and white plates if registered before 1st Jan 1979.

    I am uncertain that the  " side handrail between the cab and side" was present when all the 48xx and 58xx were built and believe it was a later addition ?

    Agreed. Most pre- and immediately post-war 48xx and 58xx photos show no side handrail. By the early 50s, most seem to have them fitted.

  8. One foot between levels sounds a bit excessive! It might be worth looking to see if that can be practicably be reduced although the gradient reduction will not be huge with a length of only 25-30' to play with. You will certainly struggle to get a worthwhile train up such a slope!

    My thinking is that it should be 0.9mm wire (1/32").  There is a discussion in the Toad build thread.

     

    John

    Hmm. 0.9mm is equivalent to over 1.5" in 7mm! From 1913 on, the GW used 3/4" gas pipe (o.d.1 1/16") for handrails - which is a little over 0.6mm in 7mm scale.

    I use Templot on my Mac (via Crossover)

    Because a plan for a small radius Y point is not available. There doesn’t even seem to be plans for the new “unifrog “ setback points out there. 

    Small radius Y points look like what they are - a horrid compromise of modelling space vs reality!

  11. Instead of enlarging 4mm scale plans, why not use the 7mm scale plans that Peco provide here? At least you are not scaling up the very narrow gauge 4mm product to an unrepresentative 7mm scale gauge.

    In the 7mm scale product descriptions, Peco claim a nominal radius of 1828mm (approx 72") for their medium radius points. You should be able to run any commercially-produced locos and stock through them without problems.
