Welcome to the Ultrascale Products web site

On this web site you will find information about Ultrascale products. Ultrascale is the name under which a range of 4mm scale items for modelling British outline steam and diesel locomotives is produced. This range includes the most common locomotive and rolling stock wheels and conversion packs for proprietary, ready to run locomotives. Most of these items can be supplied for either 'OO' Fine scale, E.M. or 18.83 gauges. Also available is a range of worm and wheel gear sets and spur gears suitable for all scales.

We can also offer a bespoke gear cutting service, to produce gears outside the current range offered on the web site. We have also developed a number of mobile apps to help in the setup, production and checking of gears.

All items are produced to order, using manual production processes, which means that lead times can be long. (see 'Current Production Status' below)
