To control access to a multi-track station, you need pre-signals. and made the loading loop a little bigger. I moved mine back a square to allow space for the tracks to merge. Stop all the trains (or be quick!), bulldoze the station, and build a new, two track one. Mardingbury is getting quite busy now, we’d like to have two tracks in the station. If you had a station half-way along a track, the lock would run right through it until the next signal. Remember, a lock is between two signals or the end of the track. If the left-hand two-way signal was not there, a train in Lundinghattan station would hold a lock on it’s two-way section of track, and the bottom part of the one-way section, up to the next signals. The two-way signals are there to prevent a train on the two-way track from locking part of the one-way loop. The only two-way signals in this picture are circled in blue. The trick is to make all shared sections of track one-way. Let’s connect up the other two towns, and not get blocked this time. As soon as it does, it will release the lock on the blue section, and the train circled in red will move forward. The train circled in blue has the lock on the blue section of track, and is about to acquire the lock on the yellow section. This is exactly the opposite to what would of happened with two-way signals. Faced with a red one-way signal and a clear track going the wrong way, the train will stop at the signal, which is nearly always what we want. Notice that it could of kept going around the loop, instead of branching off and stopping at the red signal. It is waiting for a lock on the blue section of track. The train circled in red has the lock on the red section of track, and is held at the signal circled in red. Let’s look at what’s going on in this picture. We can see the back of a one-way signal in the red circle, and the front of a one-way signal just to the right of the blue circle. We connected the shared track from Marbourne to our loading loop, with two short one-way sections. Now let’s connect our loop up to a town, and run two trains betweens those two towns. To place a one-way signal place a signal as normal, then click the signal again, once or twice depending on the orientation you want for your signal. Notice the signals around the loop are all one-way. The basic loading loopĮvery shared station should have a one-way loading loop. There is something very wrong with our approach, and the short answer is that we were using two-way tracks and two-way signals. In practice this means our Chenningpool train will head into the depot, turn around, and head back to Chenningpool. If instead of the depot we had a track running to the other side of the map, our Chenningpool would of happily headed down it, to avoid the red signal. A train faced with a red two-way signal will always avoid that signal, even if that means going away from it’s destination. The train from Chenningpool acquired the lock on the blue section, but and this is the first important concept of this tutorial, once it got level with the depot it had a choice of two paths: Mardingbury, which is blocked by a red signal, and the depot, which isn’t. Notice the two signals nearest it are red (actually all the signals in this picture are red, but focus on just those two). The Lundinghattan train is top left, just leaving Mardingbury station. The blue section is shared between the Lundinghattan train and the Chenningpool train. OK, so now you add a third station to your network. You remove that, and you have two trains sharing a station. To make that layout work, you’d need to remove the signal nearest Mardingbury, thereby merging the green and yellow sections. The train from Marbourne will be able to acquire a lock on the green section, and stop at the signal nearest Mardingbury. The signal nearest Mardingbury will be red, but the other two signals will be green. If the train from Lundinghattan Ridge is in the Mardingbury station, it will have a lock on the yellow section, but not on the green section. These signals define four locks, color coded on this screenshot. A signal locks an entire section of track from that signal until the next signal or the end of the line. When you need to connect another station, you might, unsuccessfully, try this: You can only run one train on that track, but say you’re happy with that. If you’re anything like I was, all your train layouts probably look like this: The game gets a lot more fun once you can have complex track layouts, so here’s a tutorial on train track layout and signaling for complete beginners. I have been playing Open Transport Tycoon Deluxe, or OpenTTD on and off for a while, but I confess I only understood train signals very recently.
