Virginia Railway Express riders may see delays next week as Norfolk Southern completes track work, VRE officials said.

From June 6-9, Norfolk Southern officials will be replacing the ties on the track connecting with the CSX line, just south of Alexandria. VRE officials said speed restrictions will be in place and trains will have to operate on a single track along the Manassas line.

Right now, VRE officials said, they do not know what kind of delays this work may cause. Once the work is complete, trains will have to proceed at a slower speed until a certain amount of weight passes over the tracks and officials deem that the ties are safely in place, VRE officials said.

In other rail news, VRE will make train 303 an eight-car set every Friday this summer to accommodate an increase in ridership. Train 307 will be reduced to a six-car train on Fridays. VRE officials said Manassas line train 327 is also crowded but will not be adjusted. If the number of standees rises, VRE officials said they may be able to add a car to 327 at a later date.
