In its three years, NoMa Summer Screen has shown films about the future, music and even James Bond. But perhaps no theme is more appropriate for a film series in this neighborhood north of Union Station than this year’s “Trains!” That’s right, every Wednesday evening this summer, beginning this Wednesday and ending Aug. 3, bring your blanket to the vacant lot on L Street NE between Second and Third streets for a screening of a train-related flick.

Before the screening, starting at 7 p.m., you can grab a bite from a variety of vendors, including the Sweetgreen food truck, Kool Kidz Italian Ice and barbecue purveyors Smokin’ Somethin’ (BBQ seitan is available for vegetarians). Team up to play a round of badminton or Nerf football and mingle. Then, about 9 p.m., after the sun sets against the backdrop of the rail yards, settle in for one of the following free films (for complete list of films and vendors, visit www.nomasummerscreen.com):
