Back in March 2011, BKV Zrt. (Budapest Public Transport Co.) announced a public procurement tender for reconstruction of tramline 37 in Budapest’s District X. The track closure period was only 29 days long, lasting from 9 July to 6 August 2011, making the time schedule tight: necessary tasks included superstructure demolition, substructure demolition and earthworks, drainage construction, CKT substructure construction, kerb construction, crushed aggregate lower bedding, construction of concrete sleepers and tracks, track-welding works, crushed aggregate upper bedding, fine adjustment of tracks, and construction of station platforms. Despite this tight schedule and adverse weather conditions, a timely handover was never in jeopardy. Due to mastic asphalt strips still having been hot, we could not get off at all tram-stop platforms during the trial run held at 6:00 p.m., but we were able to lift the track closure as desired by the client. Normal tram traffic resumed on 7 August 2011 morning.
