JCitron: Can we have a little explanation on what 06 and the other signals are? I am sure many other folks around here would like to know...
Sure, no problem.
The most commonly used signals, it seems to me, are as follows:
Type 04 Absolute --- used at the end of junctions where they would merge into the mainline and to guard crossovers.
Type 05 Permissive aka Home signals ---- used ahead of 04's and 06's to give warning to the driver on what's coming up. With the Jointed Rail Search Signals, they will display a solid or flashing yellow, with a flashing yellow indicating the next signal is red.
Type 06 Diverge --- These are used to guard junctions, and in particular where the track goes from double to single, they will face the single track.
When setting up a single to double track/passing siding (passing loop for those UK train fans), There is a type 06 facing the single track and one or two type 04 signals facing back on the double track.
In some cases, Type 08's are used. These are used for wye (triangle) junctions. A type 08 is setup with one each facing towards the direction of travel.
Sometimes, in particular with the older versions of Trainz, there are Type 01s, Type 02s, and Type 03s used as well. These are similar to the signals above and serve the same function. The older Type 01 is like the Type 08, and the 02 is like an 04, and the type 03 is like a permissive 06.
Hope this helps explain the signals, but using the 04, 05, 06, and 08 types has made signalling very successful for me.
