Power supply for pre-heating and pre-cooling
Efficient power management for parked rail coaches and
railcar trainsets at any track –
preheating, airconditioning and freeze protected parking
A.S.T. Power management systems ensure the power supply for preheating, airconditioning
and frost protected parking of rail coaches and railcar trainsets.
The systems have been developed in cooperation with the former BZA Munich and the DB
Energie in Frankfurt and can save up to 40% of energy compared with manual operated
preheating or airconditioning.
In doing so the parked train sets are preheated or airconditioned at a particular time at
which the coaches have to be well-temperatured for the entering passengers.
The systems are installed mainly at interchange stations or formation yards. At depots and
maintenance workshops the systems supply coaches, traction units or high speed trains
with energy.
Due to the unitized setup the system can be easily extended by new branch lines.
Switching operations and energy consumption at the specific connection points are
captured permanently by the control system and therefore can also be analysed and
allocated.

Operation mode
The supply power is either taken from the overhead contact line (11 kV, 15 kV or 25 kV) or if the
track line is not electrified from the public utility (10 kV or 20 kV).
In order to transform the energy to the required supply voltage (330 VAC, 1000 VAC, 1500 VAC)
the energy is fed via a medium voltage switch gear with a vaccum circuit breaker to
transformers. The distribution switchgear provides the tranformed current via power contactors
by cables to the cable connection boxes. From the cable connection boxes with predetermined
breaking points the energy is supplied to the coaches and railcar trainsets with a flexible rubber
hose cable using a RIC plug connection.
The operation is done at the control pillar next to the track. There the operator choses the
designated operation mode and enters the departure time of the trainset at the built-in µP time
switch. Depending on the outside temperature the time switch computes the optimal turn-on
instant for the power contactor or clocks the power contactor in order to prevent the coaches
from frost at temperatures below the freezing point.
The total system is controlled by a process computer-aided control system. There all actions of
the system are controlled, monitored and recorded. The current operation states and the activity
memory can be read out at any time via modem and analysed by software.
