Winter Train V2.0
The Winter Train V2.0 is the “second season” of the temporary LGB model railway realized for the Christmas season in the Winter Hut of Christianshavns Bådudlejning.
Version 2.0 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 result when the Winter Hut was closed for the season, December 31th 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. The “motor arrangment” changing the direction, the train will go, is called a point machine.
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 V2.0 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.
