As of 13 June 2012 part of the extension to metro line B, called B1, of the Rome public transport system has been opened. The B1 part of the line starts at Bologna and finishes at Conca d’Oro. The two stops in-between are called Sant’Agnese-Annibaliano and Libia.
Rome metro line B1
It is important to note that both line B and line B1 start at Laurentina, but that some trains after the Bologna stop veer off towards Conca d’Oro and some continue towards the end of the original line B, Rebibbia. Therefore, tourists who need to go to Rome’s second railway station Tiburtina or who, e.g., have to travel to the Ponte Mammolo stop in order to take the bus to visit Tivoli, must make sure that the the final destination Rebibbia (and not Conca d’Oro) is written on the train.
The first days after the opening of the first stretch of line B1 (which is supposed to be extended further to the stop Jonio) were extremely unsatisfying for passengers, with crowded platforms and waiting times of up to 20 minutes.
As a result of the opening of line B1 a number of bus lines have become superfluous and have thus been cancelled: 36, 36F, 90D, 342, 342F, 345.
Like the other metro lines, B1 runs from 5,30 AM until 11,30 PM (but until 1,30 AM on Fridays and Saturdays). The ticket prices are obviously also the same as for the other lines.
