The First Implementation Of ERTMS / ETCS Level 1
Free (open access)
For the first commercial ERTMSETCS Level 1 project Alcatel TAS Austria has developed the product Alcatel 6413 ALTRAC and implemented it on a 250 km section of the Sofia - Burgas line and on rolling stock at Bulgarian State Railways (BDZ). The system delivered consists of track-side and on-board equipment. The track-side system interfaces to different signal and signal lamp types (including ac and dc of different voltage and power), and the on-board system is adapted to five different 1ocomotiveEMU types. The system also is interoperable with the existing national system, a 12-bit-balise transmission system similar to EBICAB 700 (called JZG 703). Some technical solutions and implementation problems of the project will be discussed in the paper.
