London Midland train company is issuing a new timetable today, which it hopes will help with recent staffing problems.
Hundreds of trains have been affected since October, with lists of the cancelled trains appearing daily on their website.
The company blamed the loss of 30 drivers from the company within a short space of time - training replacements can take up to a year.
London Midland spokesman Daniel Skaife said: "The new timetable will kick in which gives us an opportunity to look at the way work is rostered so we can resolve the issue."
Seven new train drivers will also be starting work this month.
