The San Diego Metropolitan Transit System sold $5.1 million worth of trolley cars to the city of Mendoza, Argentina, according to a MTS press release.

MTS marketing coordinator, Jamila Hillebrand commented on the recent sale after the contract signing ceremony.

“We’re actually selling Mendoza more trolley cars,” Hillebrand said. “In 2010, they purchased 25 cars. Now they’re purchasing an additional 24.”

According to the press release, among those who attended the ceremony included Minister of Transportation of the city of Mendoza Dr. Diego Martinez Palau, Chairman of the MTS Board of Directors Harry Mathis and San Diego County Supervisor Ron Roberts.

Hillebrand said the sale is part of a project to improve trolley stations from Old Town to San Ysidro.

“It will bring money back into the system instead of using the money to repair 30 plus-year-old trolley cars,” Hillebrand said.

MTS will switch from first generation U-2 light rail trolley cars to newer cars made by Siemens that are lower to the floor.

“People can just walk on or roll their bikes on. It will be level with the platform,” Hillebrand said.

Hillebrand said MTS is halfway through with the switch.
