Dostyk railway station in Almaty oblast is the point of exit for the sole rail line between Kazakhstan and China. It should be noted that transportation costs change considerably over time; for example, between 2007 and early 2012 rail freight for 1498 km from Tobol to Aksarayskaya station (the station belonging to Kazakh railways situated in Russia) increased from USD 19.6 to USD 25.9 per tonne. Table 3.4 shows the main components of these costs based on data for exports passing through Novoishimskaya rail station, a major crossroad in the northern wheat region.
