The East Broad Top operated six Mikados, all of which survive to this day. The oldest of these is No. 12, which was christened “Millie”. Like her newer sisters, she had 48-inch diameter drivers, but was lighter and had smaller cylinders. When the EBT was reopened in 1960 as a complete heritage railway with all its equipment, number 12 remained in service with three of her sisters until she had to be retired in 2000 due to wear and tear. After the railroad had reopened in 2020 under new ownership, the locomotive remains inoperable and it remains to be seen if she will be refurbished.
