The Grey Tender Engine

The Grey Tender Engines are engines that appear in the background when at Dar es Salaam Docks as well as when Thomas meets Nia. Another is also seen when Thomas and Nia arrived in Rio de Janeiro and another one was briefly seen in Indiapulling a passenger train that later gave trouble for Thomas when it ran over a delivery of coconuts for the main station. One of the engines were also seen in China shunting in the sheds' shunting yard and later helping rerail a flatbed. These engines are reskins of Henry, the one in India shares the same whistle with Ferdinand.

Basis
Due to being reskins of Henry, the grey tender engines are based on a London, Midland & Scottish Railway's "Black Five".
