title: Crane tank locomotive
text: # Crane tank locomotive
  
  A crane tank locomotive (CT) is a steam locomotive fitted with a crane for working in railway workshops, docksides, or other industrial environments. The crane may be fitted at the front, centre or rear.
  
  The 'tank' in its name refers to water tanks mounted either side of the boiler, as cranes were usually constructed on tank locomotives (as opposed to tender locomotives) for greater mobility in the confined locations where they were normally used. There is also a crane engine in the museum of Scottish railways
