Walking, provisions and boats
Review both the destination and travel mode.
You can visit places within your current region while idle. To change regions, choose a route connected to your current location. The live panel shows its destination and whether world progress permits passage.
Walking consumes no ration. Prepared travel consumes one ration and takes 75% of the base route time. Sailing requires a carried manufactured boat, consumes one ration and takes half the base time on a water-or-towpath connection. Other earned bonuses can change the final time.
Cancelling a journey turns you back. The return takes the amount of travel time already spent; it does not instantly teleport you to the origin. Provisions already consumed for departure stay consumed.
