The Relief Station also functions the same in Evony Age 2 as in Evony Age 1. The sole purpose of the relief station is to reduce travel time between cities. This holds true for both your own cities and those of your alliance members. The bonus is applicable for both reinforcements and transports.
The reduction in travel time can be further increased by upgrading city technology of compass and hero technology of “Mount Training”.
The city technology of compass will increase the relief station reduction for both reinforcements & transport and the hero technology bonus will apply only if the hero is accompanying your troops.
The relief station reduces the travel time to 50% of actual time between level 1 & 3, 33% of actual between at level 4, 25% between level 5 & 7, 20% between level 8 & 9 and 17% of actual at level 10.
There is absolutely no effect of the relief station when you are sending attacks to enemy cities. However the City technology bonus of Compass and Hero Technology bonus of Mount Training is applicable.
I suggest you upgrade the relief station to level 9 as quickly as possible since it is hugely important during wartime reinforcements and can make or break a battle for you. The Stable is a prerequisite for the construction of the relief station.
