A visitor on the Bluefield.

In 1946, The Bluefield was considering its options for adding to its fleet of modern steam power for freight service and decided to borrow locomotives off of other roads to test their performance on the Bluefield. One of the locomotives tried was a Reading T1 4-8-4, 2103. The T1 design was the result of a collaboration between the Reading Company and Baldwin locomotive works, and they were built by elongating the boilers of several of the Reading's large 2-8-0s and building a new engine around that key component. They proved so successful that the Reading built 30 total.

In this nighttime photo, 2103 sits alongside a Bluefield P4 Pacific and a class M Mikado, the night before her trial runs were to begin. Eventually, The Big 4-8-4 was deemed to long the drivers too big for the Bluefield. After her trials, she was stored temporarily at Mount Frigid before being returned to the Reading.

in 1950, The Norkfolk and Western Railway took control of the Bluefield and Allegheny Central Railroad, but allowed to the latter road to continue to operate as a separate entity for many years.  The Bluefield benefited in the spring of that year when several of the N&W's "modern steam locomotives" showed up on the  property to help with assignments.  The Class Js rarely ever saw service on the line from Bluefield to Fairmont because their long rigid wheelbase was rough on the sharp curves common on the Bluefield. Never the less, class J 605 is captured here at the Fairmont roundhouse in May of 1950. The tender of a large articulated N&W locomotive can also be seen at the far right.
