Every train carries a number. Send it through the branch with the matching dock number.
Press the orange switch and drag over a socket. Release to commit. On desktop, click a socket; keyboard users can focus one and press Enter or Space.
A matching dock seals and the used branch closes briefly. A wrong dock, closed lane, or red maintenance gate shows the exact cause and lets you retry.
Sixty authored routes across six families and four difficulty tiers. Every board has a reachable route.
Drag the orange switch over a branch socket and release. The lime rail is a preview; the committed branch closes for the next turn.
LIME = preview / correct. RED = maintenance hazard. Numbers, hatches, and stop marks always repeat the meaning.
Every train reached its matching dock.
