The real estate and construction industries have started a full-court press, including a Web-based petition, to resurrect plans to build a stop at West 41st and Tenth Avenue for the extension of the No. 7 train line.

Over the weekend, the Real Estate Board of New York launched a Web site——so people could sign a petition to encourage elected officials to finance the stop. Currently, the line will only include one new stop, at West 34th Street. This week, both residential and commercial brokers are expected to ask tenants in buildings on the far West side near West 42nd Street to sign petitions.

There were plans to build a shell for a station on West 41st Street and then go back and build out the stop. However, a couple of months ago, plans to build the shell were abandoned.

Steven Spinola, president of REBNY, says a lot of area residents don't even know the plan to construct the shell have been shelved so the petition is an attempt to raise awareness and spur people to contact elected officials. Mr. Spinola says three construction trade organizations will be encouraging their members to sign the petition and contact elected officials. They are: The Building Congress, the Buildings & Construction Trades Council of Greater New York and the Building Trades Employers' Association.

“We think it is critical that the station be built,” Mr. Spinola said. He added the stop is vital to the continued development of the far west side, noting several developers such as Larry Silvestein recently built new residential properties nearby.

The project would also provide much needed jobs to the construction industry, which has been especially hard hit by the recession as development came to a halt.

Mr. Spinola said the industry has already reached out to the state's two U.S. senators to ask for federal help building the station. He added that signatures will be collected over the next couple of months and will be presented to various officials and agencies sometime before May, when a major building contract for the extension will be awarded.

“We've been told it would cost a lot more money to go back and build the station later,” Mr. Spinola said.

Correction: An earlier version story mistakenly said the new subway stop would be located on West 41st St. and Ninth Ave.
