Rex Metallum

Rex Metallum is a character appearing in American Rail. He is an S100 class tank engine of the USATC and is the Dallas and Northern Railroad's current No. 17. He serves as the station pilot of Dallas Terminus.

Basis
Rex is based on the S100 class 0-6-0T of the United States Army Transport Corps, specifically one of the units purchased by the Southern Railway after the end of WWII. These engines were designed to be used in Europe, though quite a few remained on US soil. The Southern Railway purchased 15 and they became known as the USA class. Four SR examples were preserved, along with over 96 other examples. An example of a US-use S100 is in operation at the California Railroad Museum.

Livery
Rex is painted in Dallas and Northern Railroad Forest Brown with gold trim.

Relationships
When he first entered service on the D&N, Rex refused to shunt a train for a "Nazi." Rex constantly called out Falken and Adalwolfa for the atrocities committed by the Third Reich during the second World War and refused to engage in meaningful conversation. Over time, however, he has opened up to them and ceased blaming them for actions they did not commit or have any control over very quickly.

Trivia

 * Rex was created for the 2013 series (minus "Metallum") as a tank engine serving a quarry in Colorado who the D&N rented for Day Out with Thomas events. The model used to represent him was a Bachmann Thomas.
 * In the 2014 series, Rex was going to be portrayed as an E2 class tank engine of the LB&SCR, reflecting his origin as a Bachmann Thomas. There was a planned episode where Rex reunited with Thomas at the 1991 Great Railway Show, which also would have introduced Evening Star (who possibly would have been a love interest of Rex).
 * Rex's name, Rex Metallum, is Latin for "Metal King."
 * Rex has been modified with a Giesl ejector.
