Mayner Posted September 22, 2014 Share Posted September 22, 2014 The recent thread on modelling Limerick Junction raised interest in building pointwork with C&L and similar systems. I am using the system on a small British Railways layout partially as a decider whether to go with flatbottom or bullhead pointwork on an Irish layout. The C&L system is based on using ABS plastic chairs and sleepers and chairs in combination with nickel silver or steel rail to represent traditional Bullhead track used on railways in the in the UK and by most of the bigger Irish Companies especially the BCDR, DSER,GNR, GSWR & NCC. On CIE this type of track was widely used on the Kerry Road, Dublin Waterford Line and Wexford Lines until re-laid with CWR in the mid late 1990s. C&L supply point kits and individual components many modellers use ply or wooden rather than plastic sleepers cheaper and more realistic. Chairs The C&L system is based on a standard 3 bolt chair for running lines and a slide chair to support the moving switch rails at the toe end of a point. A number of different types of chai are used to support the rails around the crossing and check rails in points, with C&L its basically a matter of cutting and splicing a standard chair. Some systems (Exactoscale) manufacture special chairs. Chairs threaded on to a stock rail Not as tedius as it looks quite therapeutic if you take your time Building a crossing Ready made crossing vees are expensive, I use a jig for filing and soldering the vee probably takes about 5 minutes. partially assembled V waiting to be fixed in place The metal strips are for soldering the "wing rails" in place and maintaining electrical continuity. Model points are usually assembled by first fixing the straight stock rail in place (long straight rail. Then fixing the vee and wing rails in position .... Step 1. Straight stock rail and chairs positioned Step 2. Positioning the vee using gauges. This point is built on a Templot template, the position of the crossing nose, switch and other critical details are marked on the kraft paper backing before the sleepers and ballast was laid. Steps 3-6 jumping a head too fast point almost complete You basically work across from one side to another building a point once the first stock rail and Vee is positioned the second stock rail is gauged from first stock at the toe end and from the vee at the crossing, then the blades and gut rails fixed in position. The track gauges are roller gauges, the brass gauge has sections milled out for gauging across converging rails at switches and crossings. On average it takes me an evening to build one of these points. With the formation more or next complete the next job is to install the droppers for the wiring and tie bars, then weaher the sleepers and ballast, before fixing the assembly on the layout.
