ATLAS: The road to Baseline3

Fernández Suárez, Enrique

Rodríguez, Antonio

Abstract
European Rail Traffic Management System (ERTMS) development started several
years ago, with some rail manufacturers, infrastructure managers and trains
operators, and the European Union.

Alstom was present from the beginning in this process, being the first to put in
service the ATLAS solution for ERTMS in a High Speed Line (HSL) in Italy, the first
freight line in The Netherlands, and the first high-density line with short headway
in Switzerland.

The first set of ERTMS specification, stable and complete, is based in subset 026
with version called “2.3.0 D”, also known as Baseline 2. This Baseline 2 was used
in most of the European projects today in commercial operation, and in Spain in
all the Adif (Administrador de Infraestructuras Ferroviarias), and Renfe (Public
train operator) projects.

About Spain, there are several Adif lines in operation (Madrid-Barcelona, Madrid-
Valencia, Madrid-Valladolid, etc…), and also Albacete-Alicante, the first to enter
in commercial operation with ERTMS level 2, without fall back of level 1, in May
2014.

Also Renfe has installed in some of their trains the ERTMS baseline 2, in High
Speed, regional and commuter train types.

Alstom has installed its ATLAS solution in Renfe S-100, S-104, S-114 and different
type of CIVIA trains for commuter lines. Asltom has demonstrated experience in
the ERTMS onboard equipment, with more than 5450 trainsets of 115 different
types running with ATLAS solution.
