Electrical works moving forward

31 Dec

The electrical wiring was started in 2005. The individual droppers from the rails were gathered together on tag strips from ‘All Components’ which were labelled to help with fault finding in the future. The layout is being wired in a conventional manner with 3 distinct sections – colliery, exchange and mainline. Whilst the intention will be to use DCC control, experience tells us that a better reliability is achieved using sections as an electrical fault will only shut one section down. A layout wired in the DCC 2 wires convention would suffer a total a failure in the event of an electrical fault. On an exhibition layout, we feel that the time needed to install the extra wiring will pay dividends at shows and also gives us the flexibility to run in DC only mode should the non believers want to have a play.

Point motors will be of the SEEP variety which whilst not everyone’s cup of tea have been found to be generally reliable and low cost. we use the self latching type to enable the polarity of the live frogs to be switched automatically when the point is thrown.

The point motor wiring can be seen in the yellow (alpha and beta) and green (point common) as well as the section feeds in blue (track common) and white (colliery, exchange and mainline).
