16. Double deck push-pull trains
Definition of Push-pull Train
A push-pull train is a train operated in two directions by one single locomotive only.
In one direction the train is hauled or pulled by the locomotive with the driver controlling the
train from cab located in the locomotive. In the reverse direction the train is pushed from the
same locomotive.
The rear-end car of the train is a non-powered passenger car
with an additional driver’s cab – a so-called control trailer, control cab car or pilot-car. ( TC )
Control
Loco Cab car
For operating in the reverse direction the driver will change to TC-car and control the train from
the driver’s console located herein.
The locomotive will push the train and will remain unmanned for the run in reverse direction.

29. Integration of public transportation networks and
services
Hamburger Verkehrsverbund (HVV Hamburg Transit
authority)
the first integrated public transit authority worldwide
founded 1986
intended to stop competition between guided transit
modes and bus lines
intended to offer services following the principle
– one integrated network
– one integrated timetable
– one tariff
member of GROUP 29
35. Sustainable financing for CAPEX and OPEX remains a
challenge for Germany
for new investments and extension in regional railways
we estimate 1,7 Bill €/Year
infrastructure of maintenance needs 330 Mill €/year
infrastructure maintenance backlog sums up to 2.4 Bill.€
cost recovery ratio remains under 80%, i.e. the need for
public subsidies will not disappear
but without public transit city life would sooner or later
collapse

36. Executive Summary
Commuter Railway Services in Germany is understood as a
public service obligation
Regional Commuter Railways in Germany is big business
with a turnover of more than 7.000 Mio Euro p.a.
Regional Commuter Railways in Hamburg is part of a
seamlessly integrated public transit network
Regional Commuter Railway operation has become open
for competition, infrastructure remains in hands of DB
the use of existing railway infrastructure has turned out
as a good decision to establish a sound and environmental
friendly commuter services.
