Every year about this time Model Railroader publishes its annual Model Railroad Planning magazine. Not that I am into railways across the pond, but there is always some good stuff in it, once you get used to the differences between them and us e.g. railways, language, etc. Once there was a piece about the design of pointwork to get rid of buffer locking, etc, not that American rolling stock has any, and I have applied its principles in the design of my layout which is slowly beginning to emerge. Unfortunately, we are only at the baseboard stage!
