The region's transport policysetting body is to undergo a shake-up, with councillors playing a greater role in drafting policies prior to their adoption.
The West Midlands Passenger Transport Authority, which sets policy and budgets for Centro and monitors the organisation's performance, is to move to a cabinet-style structure, similar to that adopted by most city and borough councils in the past few years.
Chairman Coun Gary Clarke (Con Walsall Streetly) said he believed replacing the "outdated committee structure" will help keep public transport at the top of the national and regional agenda.
Under the proposed new arrangements, the PTA would have a single key committee with lead portfolio holders getting more involved in policy development.
Full meetings of the authority would appoint the new lead members, then debate the main issues several times a year.
A scrutiny committee would keep a check on the effectiveness of policy and a new network of district-based transport user forums are proposed to involve members of the public across the West Midlands.
"In the last year, with a Conservative-Labour coalition at the helm, we have put passengers first, concentrated on getting things done, and delivered 100 per cent of the capital programme," said Coun Clarke.
"This re-structure is the next logical step to becoming even more effective. The job of keeping the West Midlands moving is important and urgent. We need the right structure to get the best deal for passengers and the regional economy."
Coun Clarke's aim is for the PTA to become a more effective lobbying body among MPs and to address "the South-east bias of national transport investment".
The proposed changes reflect the trend among the seven West Midlands district councils which nominate the elected members of the transport authority.
The PTA is not allowed to formally adopt a cabinet-style system under Local Government legislation. But it can move closer by streamlining the committee structure.
