Denver & Rio Grande Western In Z Scale. If you model the D&RGW you should be pleased with the increased selection of rolling stock and locomotives of late. AZL has added a nice GP-7 locomotive that is DCC ready and available in a couple of skirt variations. Also available is a nice wide vision caboose that would match up nicely with the GP-7’s. As for rolling stock, the AZL 2 bay ACF hoppers are out in 4 car sets as well as a couple of singles. These little cars are really sharp and have incredible detail. Full Throttle Z scale also offers a limited production set of two 2 cars sets of Denver & Rio Grande Western in z scale for a total of 4 road numbers. These Full Throttle car sets usually sell out fast so if you are thinking about them, don’t think to long! As interest in z scale continues to grow, so will selection of gear for all the roads. It is nice to see more of late for the D&RGW.
