Connect the two stations with a single railroad line
• The two station cells (marked with a dot) are the start and finish of the line.
• Click any other cell to mark it ✕ (no track) or place a straight/curved track piece.
• The numbers above each column and beside each row show exactly how many cells in that line contain track.
• The finished track must form one unbroken line from station to station — no branches, no extra loops.
