bigger than Rome for example), parking is a problem in Bucharest. CFR Trains In 2011, Bucharest had 99 km of railway lines, 79 of which were electric. Bucharest has several train stations throughout and around the city, the main one being Gara de Nord where trains depart to all destinations. Other main stations include Baneasa, Obor and Basarab. Gara de Nord is a relatively modern station. It was opened in 1872 and has undergone modernization and refurbishment several times. From here, trains leave to every destination in Romania and to other European cities. The other stations only see around five trains a day and are not considered "important" stations by CFR. Bucharest was once home to a vast system of industrial railways that sprawled all over the city, linking factories to the surrounding neighbourhoods and towns. However most of these are now gone and what remains has fallen into disrepair. Therefore, Bucharest didn't have an RER/S-Bahn type of commuter network until 2019 when CFR introduced commuter trains between the city and Buftea. Attempts have been made in the past to introduce such a system, but so far not much has been achieved. It is true that there are trains operated by CFR from Bucharest to neighbouring towns, however due to long journey times and poor rolling stock most people tend to use personal cars to get into the city. Road network The city's municipal road network is centred on a series of high-capacity boulevards (6 to 10 lanes), which generally radiate out from the city centre to the outskirts and are arranged in geographical axes (principally north–south, east–west and northwest–southeast). The principal and thus most congested boulevards are Calea Victoriei, Bulevardul Unirii and Șoseaua Mihai Bravu, which is the longest in Bucharest and forms a sort of semicircle around the northeastern part of the old district. The city also has two ring roads, one internal (Mihai Bravu is part of it) and one external, which are mainly used for cars that bypass the city as well as trucks, which aren't allowed in the city centre, Works on a third ring road (the A0), which would be mainly used for transit and freight traffic around the city, began in 2020 on some segments. Aside from the main roads, the city also has a number of secondary roads, which connect the main boulevards. In the historical city centre, particularly the Lipscani area,
