What Goes Into Building A Simulation?

Introduction

This FAQ attempts to explain how we develop and test a simulation. It is not authoritative as we don't always have the same sources of information or style of building a simulation.

Choosing an Area

Firstly we need to decide on a geographic area to simulate. This might be an entire signalbox, two or more signalboxes, or part of a larger signalbox. In the past we've often included entire large signalboxes as a single simulation which is great for a macro view but makes it difficult for single players to control. Nowadays we strive to balance the area covered in such a way that it is interesting by being large enough, yet not overwhelming.

We also need to have a decent amount of data for that area. Sometimes we're lucky enough to have a full set of data (more on that below); other times we're scrambling and have to deduce missing information. But if we have very little data then it's probably not worth simulating as we're striving for realism.

Data Required

• Scheme plans are scaled drawings of the track, showing block joints or axle counter head positions, the locations of signals, the identities of points/tracks/signals, platforms, and often routes. In the Western Region they have been called Locking Sketches in the past. We can work without scheme plans but it's a lot more effort.
• Satellite imagery and other mapping sources are often useful in locating features or measuring things, especially if scheme plans are missing or unclear.
