The O-Train expansion will be ready later than expected, either by mid-November
or late December, the city’s transit commission heard Wednesday.Richard Holder,
manager of the city’s light rail projects, said some testing still needs to be
completed. To switch over the O-Train from the current system to the expanded
one, which will increase service from about every 15 minutes to every eight
minutes, there will also need to be a six-day shutdown, Holder said. via
