Extending Prague Metro Line A and ongoing network construction plans

On 6 April 2015, after three years of preparation, four years of construction and 1/4 year for commissioning, passenger operations commenced on Line A (V.A section). The first work on the extension of Line A started in January 2010. After its trial operation without passengers, during which the complete technological systems both at stations and in connecting tunnels were tested, the opening of the stations followed. Also carried-out during this period were final inspections of the interior modifications of stations. The commissioning of the new section was preceded by the more than month-long replacement of the information system throughout Prague’s public transport system. All the stations of the new section, which measures 6,134km, are barrier-free.

By opening this section the overall transport network of the Prague Metro has grown to 65.2km and has a new total of 61 stations.

The history of the Line A

Construction of Metro Line A was initiated in 1973, and Table 1 on page 20 lists the dates on which the individual sections were progressively commissioned.
