Trams and trains could use existing tracks
Plans to run trains and trams on the same line in the West Midlands are being considered.
Network Rail and Centro, which is responsible for bus, rail and Midland Metro tram transport in the area, said proposals were being drawn up.
A Metro extension has already been planned between Wednesbury and Dudley.
The tram-train concept means the Metro and freight trains could share the existing two tracks on a disused line which is required for the extension.
Previous plans have included building three and sometimes four tracks on the stretch.
"I think now what central government are looking for (are) schemes that can be afforded," Geoff Inskip, from Centro, said.
"By reducing the costs undoubtedly this makes it much more feasible to bring it (the Metro extension) forward and actually deliver much earlier than otherwise would be the case."
The idea of trams and trains sharing tracks is already a reality in Germany.
