Union Station maintenance will affect RTD trains this weekend, including the A line

Travelers who plan on heading to the airport and commuters headed through Union Station should plan for rail maintenance disrupting normal Regional Transportation District (RTD) service this weekend.

The disruptions will run through Saturday and Sunday, with regular service starting back up on Monday. Union Station shuttles will pick up at Gate 5 at the underground bus concourse.

Here's what to expect:

• The A line will run a shuttle between Union Station and 38th/Blake Station, and run as normal from 38th/Blake to the airport
• The B and G lines will run a shuttle between Union Station and 41st/Fox Station, and run normally from 41st/Fox to Westminster and Wheat Ridge/Ward Stations
• The n line will run a shuttle between Union Station and 48th & Brighton/National Western Center, and run as normal from 48th through Eastlake 124th Station.

RTD said travelers should expect delays through the weekend.
