Train maintenance staff will be striking as part of the industrial action by members of the Unite Union until Thursday.
As a result there will be some changes to East Midlands Trains services.
From today until Thursday buses will replace trains on the following routes:
Nottingham - Mansfield / Worksop
Doncaster - Lincoln
Nottingham - Newark North Gate - Cleethorpes via Lincoln
Derby - Matlock
Leicester - Lincoln
The majority of services will continue to run as normal to and from London, although a number of services may operate with fewer carriages than usual.
A full train service will run to and from Skegness, Boston, Sleaford, Grantham and Nottingham.
The majority of train services will run as normal between Derby, Uttoxeter, Stoke on Trent and Crewe.
Trains between Liverpool Lime Street, Manchester and Nottingham will run as normal.
Customers travelling to and from Grantham, Peterborough, Ely and stations to Norwich may need to change trains at Nottingham - a revised rail replacement bus service will run between Nottingham and Norwich.
