what is it?
The Pennsylvania Railroad class Q1, #6130, was a single experimental steam locomotive designed for dual service. The locomotive entered service in 1942, and retired in 1949 after accumulating a relatively low 165,000 service miles. The Q1 had a 4-6-4-4 wheel arrangement, consisting of a four-wheel leading truck, two sets of driving wheels (six and four) in a rigid locomotive frame, and a four-wheel trailing truck.
