Winter Train v3

Yet another season of the temporary LGB model railway - The Winter Train - was realized in the Winter Hut of Christianshavns Bådudlejning, Copenhagen, Denmark.

Version 3.0 of this project, is a continuation of the project started in 2015. It is an ongoing development aiming at realizing a signaling system for model trains based on a simplified version of the European Standard ETCS.

These pages reflect the achieved results for the Christmas season 2017 - 2018.. Functionalities stated as deleted were not realized, but are listed here as inspiration for next versions.

A note on language is in place: The English language has several words for the mechanical track side “arrangement”, that directs a train in one of possible two directions: “turnout”, “switch”, “pair-of-point”, “point”,… At these pages, the word “point” will be used. The “motor arrangment” changing the direction, the train will go, is called a point machine.

The Danish words for “point” and “point machine” are “sporskifte” and “sporskiftedrev”

For the upcomming season 2018 - 2019 restructured documentation is on its way here.

The Team

The WinterTrain is designed and realized by: Anders Magnusson, Jan Bertelsen, Jean Perier, Mikkel Jakobsen and Steffen Mehnert. The team is located in Copenhagen, Denmark.

The project is supported by Niels Heide, Christianshavns Bådudlejning

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 V3 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. 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.
