Metro has pulled 100 of it's rail cars from service due to technical issues, and that may affect service.
The problem is with metro's doors: they open alright, while the cars are still in motion. It hasn't happened yet with passengers on board, but metro employees noticed the problem and performance tests and simulations confirmed that it could happen.
Metro officials have traced the problem to a short circuit in the motors that power the doors. It only applies to what's known as the 4000 series of metro car, which were first put in service in 1993. Officials say they don't expect service to be affected today, or possibly even into the first few days of the week as people extend their vacations. But once ridership returns to normal, passengers may notice a difference. All of the cars are expected to be back in service within 2 or 3 weeks.
