Concerns that Abellio's takeover of East Midlands Trains could lead to a route monopoly.Read more
The Competition and Markets Authority, which is investigating Abellio's acquisition of the East Midlands rail franchise, has said it's worried about price hikes on two routes used by thousands of people.
One of the lines that the CMA is concerned about runs between Norwich and Ely. The other is from Ely to Thetford.
The watchdog is worried because Abellio would operate both East Midlands Trains and Greater Anglia, which would make it the only train operator on the line.
"Thousands of people rely on this route, so it’s crucial that passengers don’t suffer as a result of reduced competition," said the CMA's Joel Bamford.
