Winter Train v4

Here we go again: Over the previous seasons the WinterTrain has developed, new functionality has been added while other has been given up. The documentation for a single feature is now spread over several pages, which even may be inconsistant.

So it is time for a cleanup…..


functional Structure In a signaling system like the ETCS each train has an On board Unit (OBU) supervising the drivers operation of the train. In order to coordinate train traffic (and to avoid collision and derailment), a central system is computing and transmitting Movement Authorities (MA) to each train. This central system consists of a Radio Block Center (RBC) dealing with movement authorities and an Interlocking System (IL) controlling and locking track side elements like points, signals and level crossings. The IL is connected to track side elements via Element Controllers (EC), which forms the electrical interface to point machines, barrier drives etc.

On top of this a Traffic Management System (TMS) is handling the overall flow of traffic (e.g. which train is going where and when). All these systems have various forms of operator interfaces (HMI).

The Winter Train V4 will include simplified versions of these elements. An OBU will be built into each train. Each OBU will have a (for good reasons) remote operator interface with wire-less connection to the OBU. This is called the Driver Machine Interface (DMI). The RBC and interlocking functionality will be realized as one system having a Human Machine Interface (HMI) for the signaller.

The figure to the right shows the overall functional structure of the Winter Train.

The signalling system will be implemented using platforms like Arduino, JeeNode and Raspberry PI.
