This set is made of stainless steel and is perfect for DC, DCC or AC using 2 or 3 rails.
DCCconcepts Rolling Roads are very easy to use… You simply place them on the track (spaced ready for your locomotive). Incredibly versatile, they help with running in, testing and evaluation of locomotive performance, active cleaning of driving wheels, simpler DCC Setup and all kinds of tweaking to be achieved in front of you, on the desk or workbench.
Rolling Roads are very versatile too - while they come pre-set for 16.5mm or OO/HO track, included in the pack are full sets of spacers for each of the following track gauges. Change takes only moments with a small screwdriver and doing it is easy and problem free for novice and expert alike:9mm or N scale, 009 and HOn30/HOe (or HO scale 3' gauge);12mm or TT, HOm (Metre gauge) (or HO scale 3'6" Narrow gauge);16.5mm or HO, OO and On30 gauge;EM and P4 finescale.
Also thought of are about those collectors and modelers who enjoy and are preserving the history of our hobby by running the 3-rail models that really kick-started the hobby.
So - to make certain the rolling roads are universal, added into all 4, 8 and 12 packs are an adapter that is suitable for both Marklin and Hornby Dublo 3-rail use - so now everyone really IS taken care of!
