During January 2007, the line was closed between Box Hill and Blackburn, to facilitate grade separation works at the Middleborough Road level crossing, near Laburnum. A rail replacement bus service operated between the two stations for the duration and, to cater for that, a temporary bus interchange was constructed at Box Hill. The interchange was built directly on top of the tracks, which had been paved between the rails to the east of the station, and was connected to Platforms 2 and 3 via a raised walkway. With the completion of the major works at the end of January 2007, the bus interchange was removed.
