Track changes to SkyTrain’s Expo Line this weekend, Sept. 23–24

Track changes to SkyTrain’s Expo Line this weekend, Sept. 23–24

Crews install a 60-foot section of curved rail near Main Street–Science World Station back in May 2017.

Are you planning to take the SkyTrain’s Expo Line between 11:30 p.m.  10:30 p.m. on Saturday, September 23 through 3 p.m. on Sunday, September 24? Please plan for an additional 15–20 minutes of travel time as service will be modified for rail replacement work.

During these times, trains will use a single track in both directions near Commercial–Broadway and Main Street–Science World stations. As well, all Expo Line trains will operate between Waterfront and King George. If you are travelling to Production Way–University, Lougheed Town Centre, Braid or Sapperton, you’ll need transfer to the Special SkyTrain Service (see map) at New Westminster, Columbia or Commercial–Broadway stations.

Please watch for destination displays and listen for announcements. The Millennium Line will operate at normal frequency and the Canada Line is unaffected by this work.

On Sunday, Sept. 24 from 7 a.m. to 3 p.m., all Expo Line trains will operate between Waterfront and King George stations only. A Special SkyTrain Service will operate between New Westminster and VCC-Clark.

Why can’t this work be done overnight?

Crews will be replacing a curved section of rail just west of Main Street-Science World Station—and it’s no easy feat! This curve is the sharpest on the SkyTrain network outside of the Operations and Maintenance Centre, near Edmonds Station.

One side of the curved track was replaced back in May 2017, and now the crews are back to complete the other side.

The unique nature of curved tracks means the 60-foot rails need to be pre-bent off-site and transported to the work area on flatbed trucks for installation. Once there, the track is greeted by a crane and lifted into place at the track level from the roadway. Normally, replacement rail is transported on the guideway to the work area, but this isn’t possible for curved rail.

This curved-rail work requires 15 continuous hours so the regular overnight maintenance window doesn’t provide enough time.

We thank our customers for their patience while we complete this essential work.
