Motorway drivers have been warned to expect delays when an abnormally large load makes its way through the county tomorrow.
A Class 92 railway locomotive is due begin its journey on a trailer from a service station on the M25 to Loughborough at about 5am.
The 138-ton locomotive's journey, which is estimated to take up to six hours, is due to take it along the M1 to junction 23 - the exit for Loughborough.
The locomotive arrived in Folkestone today and was being winched onto a trailer.
A spokesman for the Highways Agency said the lorry and trailer would only take up one lane but would not exceed 30mph.
The locomotive is being taken to Brush Traction rail engineers in Loughborough for a refurbishment.
A spokesman for GB Railfreight said the locomotive is used for pulling trains through the Channel Tunnel.
