CMA warns train passengers face higher prices if Abellio takes on East

fares on two routes it is probing as part of an investigation into
Abellio’s acquisition of the East Midlands franchise.

Abellio’s ownership of Greater Anglia means it would operate a monopoly on
the Norwich to Ely and Thetford to Ely routes as it would then also operate
East Midlands Trains, the Competition and Markets Authority (CMA) warned.
