Gradients have always posed a problem to model railway builders. MIKE WILD tackles the subject using DCC Concepts Powerbase equipment to install two gradients on our much modified ‘N’ gauge office test track, with impressive results.
NO MATTER what scale or gauge you model in gradients have long posed a problem to modellers and in British circles they are comparatively rare. In European and American modelling circles gradients have long been part of layout construction where design spaces either call for or allow for these challenging features to be installed.
Gradients are equally challenging for the full size railway too. Steel wheels on steel rails can only create a certain level of friction – which in turn becomes adhesion. Increase the gradient too much, or increase the weight of the train beyond the capabilities of a locomotive, and all of sudden problems will arise and the locomotive will struggle to cope with moving its load forwards.
Above: The completed storage yard features 14 tracks – eight on the level on the lower section and six on the 1-in-68 incline. This type of storage yard has radically improved the operational flexibility and enjoyment of this layout instantly.
On the real railway some of the steepest banks…
