The Winter Train V1.0
The Winter Train V1.0 is a temporary LGB model railway realized for the Christmas season 2015 in the Winter Hut of Christianshavns Bådudlejning. But it is also an ongoing project aiming at realizing a signaling system for model trains based on a simplified version of ETCS.
These pages reflect the achieved result as of New Year, January 1st 2016. 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 two possible directions: “turnout”, “switch”, “pair-of-point”, “point”,… At these pages, the word “point” will be used.
Overview
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 the track side elements (e.g. points and level crossings). 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.
The Winter Train V1.0 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.
