Single unit loco lift. Designed as a replacement for the old SL-43 Loco Lift, this new versatile system still has the features that made the SL-43 so popular, such as the ability to directly drive the locomotive on and off the track. But that was limited to OO/HO scale and this new system has been developed to adapt to all scales from N through to EM, including OO-9 (HOe), HOn3, TT, HOm and OO/HO.ÂÂ
