This year was the debut of Mavis for the American Day Out with Thomas franchise, which was achieved by masking Strasburg's 8618. Paired along with the replica of Thomas that actually runs on steam, and the GW 90 on regular trains, it was a sight to behold.
Also featured is a cameo appearance of 611.
