Upper Underrail metro

C2X locomotive

Trains of the eponymous Underrail metro network.

The upper metro is the residential area of Underrail. It is divided into three main metro lines - blue, green and orange. The trains don't visit all the stations on the network, so some are accessible only on foot. Upper Underrail can be accessed via Core City's main elevator.

Upper metro routes

• Polemos Station (Fort Apogee) ↔ Epione Lab ↔ University Station (Institute of Tchort) ↔ Core City (25 Stygian Coin)

For other upper metro stations, see Upper Underrail.

Lower Underrail metro

C2X locomotive

Trains of the eponymous Underrail metro network. Drivers manuals for the C2X train engine can be found scattered around Lower Underrail.

The lower metro is consists of cargo lines for the industrial and military complexes of Lower Underrail. The trains, powered by old-fashioned locomotives, have both cargo and passenger cars. Lower metro travel is initially unavailable due to an earthquake that collapsed south metro tunnel leading to SGS, but metro travel in Lower Underrail becomes accessible the next day after player finds drill parts for SGS and the tunnel is cleared.

Lower metro routes

• South Gate Station ↔ Rail Crossing ↔ Foundry ↔ Core City (25 Stygian Coin)

Lower Caves ferry

A typical ferry boat

The vehicle of choice for both cargo and personnel transfer via the natural underground streams and lakes in the Caves below Lower Underrail.

Ferry boat captains move cargo and personnel between major settlements of the caves for a fee, and the underground rivers are also common smuggling routes.

Ferry routes

• South Gate Station (25 SGS Credits or 8 Stygian Coin) ↔ Junkyard (10 Stygian Coin) ↔ Camp Hathor (10 Stygian Coin) ↔ Core City (20 Stygian Coin)
• Junkyard (10 Stygian Coin) ↔ Silent Isle
• South Gate Station (300 Stygian Coin) ↔ Forsaken Island (only once)
