Under the Networks folder is an additional folder set. This is because a network structure applies to Track, Roads and Lofted Objects (such as walls and fences). Their creation is all completed using the Linear Object Tools.

The tiles within these folders are named in the same way as other tiles. They contain position information about track, roads and lofted objects respectively. 

In particular, the tracks.bin file is probably considered the most important file of a route. This file contains all the data of the track as well as all objects linked to the track. These include (but are not limited to) Signals, Speed Signs, Platform and Siding Markers, etc.

We recommend that during route creation regular backups of the tracks.bin and track tiles are taken.
