939:. Franklin Type B gear was applied to a handful of locomotives starting in 1948, including K4s 3847, which had been designed or built with conventional piston valves. Type B2 was devised specifically for the T1 as the existing valve arrangement from the Type A gear differed from Type B. 5500, perhaps the first locomotive fitted with two types of poppet valve gear, was soon noted for its superior performance over the other engines of its class. The Pennsylvania Railroad at one point even considered retrofitting the Type B2 poppets to other T1's, but this action was never taken. It is worth noting the Pennsylvania Railroad also experimented with the idea of fitting the conventional

By November 2016, most of the scanning work had been completed with 1,638 of the 1,798 needed drawings and blueprints having been scanned and acquired by the T1 Trust. Only 150 of the drawings are missing from the collection, and these are composed mainly of simple fasteners and other readily-available, commercial components. The digitally-scanned drawings collected by the T1 Trust are used to create detailed and intricate 3D Models using the

In 1947, a higher-strength and fatigue-resistant alloy was used and retrofitted to the T1 class to solve the fatigue problems. Nevertheless, the design of the Franklin Type A poppet valves made several key areas of the valves hard to access during maintenance overhauls. Despite these issues, the poppet valves did improve the T1's high-speed performance, requiring less horsepower and distributing steam flow with greater precision. The T1 locomotives were further burdened by excessive

To help fund the tender restoration, the Trust has created a separate donation fund for this task and will display the names of all donors who pledge $ 500 or higher to the fund on a bronze plaque placed upon the tender itself. The total cost of the tender restoration is estimated to be more than $ 50,000. On October 5, 2017, an automatic coal stoker was donated to the Trust. The motor, coal crusher, gearbox, stoker trough, and reversing valve were donated by Gary Bensman and Warren Lathom.

The T1 Trust hopes to do a full inspection and documentation of key features within the Type D poppets to use as a basis for reconstructing the Type B2 poppets proposed for use on 5550. It is also hoped that the investigative work and documentation can aid a future restoration of USATC 611. The P2 Steam Locomotive Company is also planning on using the Franklin Type B Rotary Cam poppet valve (albeit the earlier B1 model) for the proposed new build

Scrapping began in 1953, and the last surviving T1 was scrapped in 1956. The hasty retirement of the T1 left several performance-related and technical questions unanswered.
