Elevations of Stations I, II and III are +104Bm, +9CDm and +11.4Dm respectively. The distance between Stations I and II is 10km and the distance between Stations II and III is 12km. Ckm-length tunnel is placed between Stations I and II, and Bkm-length curves with 2100m radius are placed between Stations II and III. The tunnel resistance is 2kg/t, curve resistance is 700/R kg/t and running resistance is = 3 + (kg/t. 4.1. Draw the railway track profile schematically and calculate the gradient in the tunnel. (10p) 4.2. Analyze whether the gradient applied on the curve sections has negative gradient or not for a train having a regime speed of 160 km/h.
