had been guaranteed the safety since 1935, that means 72 years!). On the same summer at the Cegléd station,
the first SIMIS IS interlocking from Siemens was taken into operation. From two aspects it was very important: this was the first station, where a Domino55 was replaced and this was the first case, when the track building layout phases were followed an electronic interlocking (normally MÁV uses the old, or a temporary relay-based interlocking for this purpose).
only in December of 2008 was it taken into operation. This area comprises three stations: Zalabér-Batyk (as area centre with AKF MMI), Ötvös and Pókaszepetk (remote controlled stations without local control possibility). Three stations of the Zalaszentiván control centre (Zalaszentiván, Zalaegerszeg delta and Andráshida) went into operation in May 2009, the remaining section (Ukk are centre: Ukk, Nemeskeresztúr-Jánosháza and Jánosháza branch) has operated since December 2009.
interlocking taken into operation on the MÁV network. But thankfully in 2011 the ‘silence’ was broken when two large call-for-tenders for electronic interlocking appeared. One of them was awarded by Siemens: Kelenföld (excl.) – Székesfehérvár (excl.) line with six stations, centralised electronic block interlocking and electronic open line level crossings. The other one awarded by Thales: Szajol (excl.) – Püspökladány (incl.) line section with five stations, centralised electronic block inter -
Map of Hungary and the current status of work
In summer of 2008, the old Domino55
interlocking of Győr station was replaced by an Elektra2; this was the first one of this type in Hungary – not with AKF but with EBO2. Siemens awarded the contract for three
stations of Szajol (incl.) – Mezőtúr (excl.) line section. During the last months of 2008, electronic interlocking of Szajol, Tiszatenyő and Kétpó were taken into operation; each station is operated from Szajol ILTIS MMI, but Tiszatenyő has its own local control possibility. Because of long track reconstruction time,
the first control area of the Boba–Zalalövő line section (as continuation of Hungarian–Slovenia railway connection in operation since 2002)

Only area centres have AKF MMI, but the whole Boba (excl.) – Őriszentpéter (incl.) can be controlled from Zalaszentiván CTC; fortunately, in this project the Zalalövő area EBO1 MMIs (Zalalövő and Őriszentpéter) were replaced by AKF. In September 2009, the last contract
awarded up to 2007 was fulfilled: Pestszentlőrinc station was taken into operation. It is locally controlled, but remote control possibility is available from Kőbánya-Kispest.
The close future… Unfortunately, for quite some time from December 2009 there was no new electronic
locking (on the double track main line and towards adjacent secondary lines) and electronic open line level crossings. Because MÁV uses only decentralised relay block system up to now, centralised block system is a great challenge for suppliers and for MÁV as well. Moreover, both projects comprise RBCs for ETCS L2, therefore realising of interfaces between RBC and interlocking is task for manufacturers. In November of 2011, a new tender came
out: a section of the Budapest–Esztergom line. In frame of this project, five stations (Óbuda, Solymár, Pilisvörösvár, Terranova and Piliscsaba) shall be equipped with new electronic interlocking. A further project might appear
