Metropolitan Line train.

UK: ‘Creative and holistic’ proposals are being sought from suppliers, operators and research organisations interested in partnering with Hertfordshire County Council to develop conceptual designs for ‘a new and future-ready transport system’ linking Watford Junction and Croxley using a disused rail alignment

The council plans to appoint a number of consortia early next year to independently develop ideas based on a wide range of potential options, including active travel, e-mobility, autonomous shared mobility such as pod vehicles or various forms of mass rapid transit.

The council would oversee the development of design concepts in collaboration with Watford Borough and Three Rivers councils, Network Rail and Transport for London.

The previous Croxley Rail Link project to divert London Underground’s Metropolitan Line over the disused railway was granted legal powers in 2013, with opening initially planned for 2016. However, costs increased and the scheme was eventually cancelled as being unaffordable.

Earlier this year Steer produced an updated report into strategic transport needs in the corridor.
