This “HO” scale Pennsylvania Class T1 4-4-4-4 Duplex Drive locomotive fleet number 5513 in plain black livery is built from cast and brass components including brass etchings. The model has been extensively cleaned and serviced with a limited number of minor restorations undertaken. It is in running order and powered by two motor-gearboxes. The engine and tender have an insulated flexible tow bar secured in place by threaded bolts with lefthand power collection via the engine and righthand power collected rom the tender. Prototypically, these locomotives were a success, able to pull 16 cars at 100 miles per hour. The enormous 16-wheeled tenders enabled the locomotive to run from Harrisburg to Chicago with one intermediate coaling stop and wayside track pans for retanking water. 50 Locomotives numbered 5500 upwards were built by Baldwin and Juniata once the post-war restrictions were lifted. The model is quite heavy and will be suitably boxed but it will require careful handling.
