Over the last few weeks, I have been revisiting a number of model coaches that I have built in the past, typically quite some time in the past as most of these have been around since either my teens or twentys!
Over the years techniques have changed and I undoubtedly would not build most of them in the manner that I originally built them if I was confronted with doing them again. Having said this, on the whole my handiwork – especially in respect of the painting and lining was really quite good. I seem to have lost my lining mojo in particular, so I am not sure I could line as well as this now. This is something that I really must get to grips with this, as I still have a lot to do!
But the biggest area of difficulty with the coaches is that the bogies were generally formed around beam compensation units. These are OK for a couple of coaches behind a branch train but they impart far too much friction for a full main-line train as I aspire too. This is impossible to overcome whilst retaining the compensation units, the bar is the cause of the problem and it has to go!
To overcome this, Bill Bedford sprung boiges are being retro-fitting to all of my existing stock. These rely on separate hornblocks that secure a pin-point bearing in them – so rolling resistance is significantly reduced. The hornblocks are held in place by way of guitar wire and the effect is that they glide around the trackwork. They thus give the impression of weight and inertia that is much better than compensation (it is possible to get compensation that does not use the rocking beams that are the cause of the fritchion I am complaining about).
The Bill Bedford units are only an inner bogie and they still need to have some form of detailing on the outside. Some of these have entirely cosmetic outers, either of plastic or white metal but the two Midland coaches and the Highland TPO have something slightly different. On these, I utilised the original etched bogie sides and laminated them onto the Bill Bedford inners. This is very successful as it improves the Bill Bedfords notably by making them a lot stiffer and you get the crispness of the etching process.
If, by the way you fancy some Fox Pressed Steel bogies that are neatly sprung and look the part - and almost all pre-group modellers ought to - keep watching the space. Subject to a test build or two, there will shortly be one available on the market.
To test them, I took them and a few other coaches to ExpoEM to use their test track. Here we see a Barney with eight on – albeit a rather od mix for the train and there is a fair amount of painting and lining still to be done.
And to prove that they really do work and also to allow you to see how they glide, a quick youtube video: https://www.youtube.com/watch?v=6D7a_cW ... e=youtu.be
