Coronel Church

Coronel Church is a metre-gauge tender engine from 1878 belonging to the Estrada de Ferro Madeira Mamore (EFMM), a Brazilian railway. The name is based on the nickname of George Earl Church, an American civil engineer who conducted the survey of this railway laying.

The locomotive was abandoned for 30 years and discovered consumed by the rainforest, after which it was repaired and steamed again, running for another 30 years. The locomotive is currently at the EFMM Railway Museum in Porto Velho, Rondonia, Brazil.

According to Wilbert Awdry, the locomotive's rediscovery was the inspiration for Duke and for that reason it was mentioned in the foreword of the twenty-fifth book of The Railway Series, Duke the Lost Engine.
