股道編號標誌
Tracks with IDs are station tracks with unique addresses. These addresses allow them to be referred to in delivery orders, as well as to navigate to them with station maps.
Other than in books, track IDs are also shown on physical signs. Track ID signs are pole-mounted structures found on the right side of the respective tracks, on their both ends, designed to inform of their ID. Regardless of the signs' positions, however, the address spans the entire track from switch to switch.
股道編號中的最後一個字母則用於標示對應股道的用途。例如：
I - 到達線（Input）
此為貨運列車到達的軌道。
O - 出發線（Output）
此為貨運列車配發的軌道。
S - 留置線（Storage）
L - 貨運裝卸線（Cargo Transfer）
此為以貨物轉裝機為車輛裝卸貨物的軌道。
LP - 客運線（Passenger Transfer）
此為附有月台，供乘客和郵件上下的軌道。
SP – 客車留置線（Passenger Storage）
為停放客車和機動車輛的地方。
Tracks with IDs shouldn't be blocked with unexpected vehicles, because this could disrupt the proper delivery order generation.
