The Metropolitan Transportation Authority is chugging along on the 7 line extension. 

The agency is now training its operators and dispatchers how to navigate the new 34th Street - Hudson Yards station. 

In all, 12 tower operators, 8 dispatchers, and nearly 700 train operators will be trained on the route by the end of the month. 

The MTA says the station will open this summer, with an official opening date to be released in the next few weeks.
