Stacked ends not connected
Work in progress: This section is still a work in progress — content is being added and revised continuously.
What is checked? Whether two track ends lie exactly on top of each other without being connected. This means ends that would have connected: at the same joint, facing each other and from track that fits together, even when the two tracks are on different layers. Every such pair is reported with the height difference between the two ends.
Why does it matter? From above the joint looks finished, but the track ends here. Usually the height keeps the two ends apart: the Trackplanner only connects two ends when their heights match as well. If one sits 1 cm higher than the other, the Trackplanner lines up the track you drag but does not connect it, and the plan shows no visible difference.
How to fix it: Open the finding in the plan check and choose “Show fix”: the quick fix connects the two ends and evens out the height, with Premium when there is a height difference. Or in the Tracks tool tap ⋯ at the end, choose “connect” and tap the end underneath. When such a pair has only just appeared, for example right after a drag, the Trackplanner offers to connect it above the joint. The preview shows how the height is evened out, usually as a shallow ramp over the track leading up to the joint.
Numbers & defaults: Ends count as lying on top of each other when they are at most 2 mm apart (H0, scaled by gauge; 6 mm between two pieces of a toy system) and kinked by no more than 3°, which is as close as two ends must be for a new connection. They are reported up to just below the vertical clearance (H0: 8 cm, scaled by gauge), and between two pieces of a toy system up to just below 3.2 cm, because the second level sits lower there (the wooden railway ramp rises 6.4 cm). Ends stacked even further apart are almost always an intended second level, such as a staging yard or a bridge.
