This now has Hex to Decimal conversion and Octal to Decimal conversion.

Now has two separate pairs of trains sharing track. One with trains using a switch out to share a single track. The other has two separate routes that share a portion of track.
There are also several methods of handling buffered load-outs

I have two trains sharing a single track working in my mod now. Get the latest version. Look at the test track (the loop near the PackingHouses). There is a circuit to the right with several Billboards. It uses parity to keep two trains synchronized, four pairs of Gates, Toggles and AgentSensors.

It's a bit arcane but it seems to work well.

There is a different configuration with two trains crossing and sharing a piece of track on the opposite corner of the map.

Circuits can be a bit confusing to decipher. I haven't converted these to my Pipes and Blocks configuration yet though I will likely get around to doing so.
