"We can confirm that there was a fire between the conductor rail and the shoe gear beneath the 05.55 train from Weymouth to London Waterloo earlier this morning.
"None of the 20 passengers or staff on board were injured in the incident and the train crew quickly extinguished the small fire.
"Emergency services were called as a precaution. The problem with the shoe gear was at the front of the train and as a precaution two passengers were moved to the rear coach of the train where the other customers were seated.
"A bus replacement service was put in place between between Dorchester South and Weymouth while the train was moved and normal services were running by just after 9am.
"We would like to apologise to our passengers for any inconvenience caused."
