A £60 million project to run tram-trains between Sheffield and Rotherham is moving into its next phase as the vehicles that will be used are built in Spain.
The long-awaited scheme – first announced in 2009 – has been delayed several times but is now due to be up and running by early 2017.
Seven special vehicles are being built in Valencia and are due to be tested soon before being transported to South Yorkshire.
A South Yorkshire Passenger Transport Executive spokesman said: “The first tram train vehicle will arrive in the UK in November 2015.
“After the vehicles have been tested, tram-trains will operate on the existing Stagecoach Supertram network to enhance capacity during peak times.
“Tram-train customer services between Sheffield and Rotherham are expected to run from early 2017.”
The project will provide a direct service between Sheffield city centre, Rotherham Central train station and Parkgate retail park.
The Stagecoach-operated scheme is intended to allow specialist vehicles to use the existing Supertram route between Cathedral and Meadowhall South and then move onto the rail network via the new track to Parkgate.
The partners in the project are Network Rail, Department for Transport, Northern Rail, South Yorkshire Passenger Transport Executive and Stagecoach Supertram.
It is intended three tramtrain services will run each hour.
The scheme will run as a pilot project for an initial two years and will become permanent after that should the initiative be judged a success.
It is expected to create 35 new jobs.
