As the Gauge 1 Model Railway Association celebrates its 75th birthday, we visit the president's own line, with a show of many of the locos he has designed.

We're getting technical with a look at gearboxes for battery-powered models, building a 4WD Simplex with plenty of grunt, a mine and concrete huts, suggesting the top 10 tools for your workbench – and starting our biggest project yet, building a live steam locomotive from a kit.

All this and the latest Product News for the large-scale model railway enthusiast.
