The Walthers Cornerstone 3 - Stall Modern Roundhouse is a must - have for later steam - era railroad layouts. These add - on stalls let you customize and expand your roundhouse to fit your layout's needs. In any 24 - hour period, the number of engines in and out determined the roundhouse size, with the busiest terminals needing full - circle ones. So, these extra stalls are perfect for matching your roundhouse to your setup. This detailed 3 - Add - On Stalls kit features three stalls on 10 - degree centers, just like the real thing, making the most of your available space. The side walls come with the separately sold Modern Roundhouse kit 933 - 3260. It has tons of realistic details like interior and exterior brick walls, fine windows, floor inspection pits, and decal signs. It's modular, easy to expand to a full circle, can hold engines up to 125 scale feet long, and has a compact 10 - degree stall spacing. Kit size: 10 - 13/16 x 3 - 15/16' (27.4 x 10cm); Stall Width at Rear: 3 - 3/16' (8.1cm).

Using this Walthers Modern Roundhouse Add - On Stall is easy. First, make sure you have the main Modern Roundhouse kit 933 - 3260 as the side walls come with it. Then, simply attach these add - on stalls to the main roundhouse according to your layout plan. When handling the kit, be careful with the fine details like the windows and decal signs to avoid any damage. For maintenance, keep it in a dry place to prevent the brick details from getting damaged. You can use a soft brush to gently clean the dust off the kit every once in a while. Also, if you plan to expand it to a full - circle roundhouse later, arrange the stalls carefully to ensure a proper fit.
