A steam train, powered by coal or wood. An early type of locomotive, now mostly replaced by electric or diesel trains.
Oddly, this emoji does not show any steam coming from the train.
Locomotive was approved as part of Unicode 6.0 in 2010 under the name “Steam Locomotive” and added to Emoji 1.0 in 2015.
