Data from FW&DC 8 - 1942 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 40229-40234 in June 1906.
These Ten-wheelers were large, robust, saturated-steam engines when they arrived on the FW & DC as the lion's share of an order that included a pair of locomotives for the Colorado & Southern.
According to Drury (1993), they were superheated and fitted with Walschaert gear in 1919-1920, but the 1942 book shows no sign of such an upgrade. The C & S locomotives shown in Locobase 6755 are likely to be identical to the FW & DCs after the latter's reconfiguration.

These Virginians appear to have had the same general design as the Brooks locomotives shown in Locobase 9851. The boiler was less crowded, the grate a little smaller, but the firebox heating surface was about the same. Cylinder diameter grew by an inch, possibly to counterbalance the adoption of taller drivers.
According to Drury (1993), they were superheated and fitted with Walschaert gear in 1919-1920, but the 1942 book shows no sign of such an upgrade. The Colorado & Southern locomotives described in Locobase 6756 are most likely representative except that they had 67" drivers.
