A new model of train fell short of a full day’s work, as the R179 from manufacturers Bombardier Transportation failed the Sunday test the Metropolitan Transportation Authority put it through and was yanked early, according to the New York Daily News.

“The testing process involves putting cars into service and routinely reviewing their performance,” MTA spokesman Shams Tarek said.

The Daily News reports:

First, the train’s emergency brakes kicked in when it ran over a blue bucket that apparently flew onto the tracks from the platform of the 121st St./Jamaica Ave. station on the J line in Queens around 12:15 p.m., crews reported to the MTA. Riders were forced to leave the train at the next Manhattan-bound stop.

The woes on the tracks continued hours later around 7:30 p.m. when the train had to be taken out of service.

A display-screen console on board showed the doors were open in one of the cars as it pulled into the J line’s 111th St./Jamaica Ave. station. Bombardier personnel on board at the time reported that it was a faulty message, but the R179 model has been sidelined since then.

The new trains from Bombardier Transportation were originally expected to be delivered in 2014, but they didn’t arrive in New York until September of last year, according to AM New York. The MTA paid $740 million for the manufacturer to build a new fleet of 300 cars.

The MTA remains positive about the new trains. Tarek said the testing on the new model will continue Friday.

“We’re looking forward to fully deploying these trains,” Tarek said.
