Altoona

Altoona is a character appearing in American Rail. He is a K4s of the Pennsylvania Railroad and is the Dallas and Northern Railroad's current No. 14. He is used for main line passenger trains.

Basis
Altoona is based on the K4s class of the Pennsylvania Railroad. These were among the PRR's most famous locomotives, and Sir Nigel Gresley took inspiration from them when developing the LNER's A1s. Two were preserved, and the class is considered the official locomotive of Pennsylvania.

Hank, in the Thomas and Friends Television series, is a member of this class.
