While Metro Line 4 is under construction, the complex reconstruction of Metro Line 2 is near completion. This has been the largest transport project in Budapest in the past two decades. The reconstruction work had to be designed, organised and completed causing the least disruption possible to passengers. The history of the project is described, including reasons forthe need for this radical up-grade. These included building deficiencies in the original construction; natural wear and tear; operational safety issues; and the need to replace obsolete technical equipment. A table summarises the predicted lifespan of major parts of the infrastructure. The reconstruction of major systems include waterproofing repairs of underground structures; architectural reconstruction of stations; renovation of railwaytracks; renovation of railway telecommunications equipment; renovation ofpower supply equipment; replacement of railway safety and train control equipment; renewal of vehicle stock; replacement and construction of escalators and lifts; renovation of specialist machinery and equipment; fire protection development; and modernisation of passenger information and ticketvalidation equipment. The business administration attached to these projects is described in more detail and a summary of completion dates for someof the projects is provided.
