The Big Dipper

The Big Dipper is a large two-track viaduct made of stone. When Mr. Conductor was captured by Diesel 10, he discovered that the bridge had begun to collapse as a result of the world losing its energy, caused by his gold dust crisis. Diesel 10 fell into the river below after failing to jump the gap when in pursuit of Thomas and Lady. It is unknown if it was repaired afterwards. It is assumed that the Big Dipper was never seen again.

It is not to be confused with The Viaduct, Hoo Valley Viaduct, Callan Viaduct, or the viaduct mentioned in Haunted Henry.
