Tips for Train Signals

Follow one train line at a time in the direction the train will travel. If there is a segment of track that you do not want your train to potentially stop in (such as an intersection), use a chain signal at the point where it can enter that segment.

Otherwise use the normal ones. Those are the fundamental concepts. The other stuff is just a more involved use of them.

If you follow your train down the track…

For Normal Signals:

Only 1 train can occupy any portion of the track between 2 normal signals at a time.

  • Normal – >Train> – Normal – >Train> – Normal

For Chain Signals:

Only 1 train can occupy any portion of the track between the chain signal and the segment after the next normal signal at a time. The space after needs to be clear and have enough room so the train passing through has someplace it can go.

  • Normal – >Train> – {Chain – Normal} – >Train> – Normal (Train will not pass through)
  • Normal – >Train> – {Chain – Normal} – Empty – Normal (Train will pass through if room)

For intersections, remember to just follow one path at a time through the intersection and signal accordingly. Do that for each path through the intersection that a train could take and you should be fine. You can do more robust things with intersections using more chain signals but these are the basics.

I turned my love for games from a hobby into a job back in 2005, since then working on various gaming / entertainment websites. But in 2016 I finally created my first website about video games – Gameplay Tips. And exactly 4 years later, Game Cheat Codes was created – my second website dedicated to legal game cheats. My experience with games started back in 1994 with the Metal Mutant game on ZX Spectrum computer. And since then, I’ve been playing on anything from consoles, to mobile devices.
