Railway Empire 2

In Railway Empire 2 there are Freight trains, Express trains, or Mixed. The default is mixed, so to have this achievement we need to make a new Rail Line, connecting two cities' stations, and then on the screen where you choose your locomotive select the Express option. This ensures only passengers and mail are picked up which in turn gives the train "express" status (after it's been back and forth between the stations at a decent speed).
