# Suburban trains in Budapest

Suburban trains in Budapest are known in Hungarian as Budapesti elővárosi vonatok, serving fourteen lines in the Budapest metropolitan area, three of which are part of the BHÉV system. The system is operated by Hungarian State Railways.

## Services

The HÉV lines are indicated by a H letter followed by a number. H5 terminates at Szentendre, H6 at Ráckeve, H8 at Gödöllő and 9 at Csömör. H7 does not cross the administrative boundary of Budapest. The numbering was introduced in 2011, continuing with the numbering of the existing M4 subway line.
From 15 December 2013, suburban trains departing from the Budapest-Déli Railway Terminal were piloted, and from 14 December 2014 all suburban trains received numbered services.
Trains that stop at every station are designated as S (similar to numerous S-train services), trains making fewer stops are designated as G, and express trains are designated as Z.

Between the Budapest-Kelenföld and Ferencváros stations, the construction of the third and in some sections the fourth track will be built, in addition to the complete renovation of the existing tracks.
New stations are being built at Közvágóhíd and Újbuda under the name Nádorkert.
