The twelfth Bandai Thomas Town series was released in October 2004 and included three new characters and a new track layout. It had the subtitle お仕事がんばろう!編 or Let's Work Hard! Edition.
At this point some of the new molds for Thomas Town and Pocket Fantasy characters began to diverge, with Emily and Spencer getting different toolings for the Pocket Fantasy range.
Thomas includes a bridge with three telegraph poles and a curve with a farmhouse with a turning weathervane.
Terence has a curving rail section with a ramp up to a platform where Terence can push over a large hinged rock, with two other small separate rock pieces also included.
Spencer included a straight section with stop gate, signal, and station. Spencer has black buffer stickers, something seen in a few Thomas Town series in the mid 2000s.
Emily included a curved docks section with rotating crane, lighthouse, and barge. Emily also has buffer stickers...
Percy included a wide turnout and a connecting curve with a coal loading chute.
I have a few of the track sections from this series, like the neat Terence loading ramp, but pretty much all of the cool accessories are missing.
