The Camp Hill line stations closed during 1941 and since then the line has been used only by freight and non-stop passenger services.

Reopening for passenger services involves constructing three stations at Moseley, Kings Heath and Hazelwell including supporting rail infrastructure works.

These new stations will provide regular train services into Birmingham New Street, with quick journey times offering commuters a genuine alternative to their car.

Authority procurement chiefs plan to use an NEC 4 target cost contract including clause X1 to alleviate contractors’ risk on material price fluctuations on volatile material like timber, concrete and steel.

Firms have until the end of August to submit an interest in bidding for all three stations. Shortlisted firms will then be invited to bid on 30 September.
