THE CALCULATION OF THE UPPER & LOWER COMPONENTS OF THE NEW RAILWAY ROAD IN DEAD LINES REACTIVATION IN BABAT-JOMBANG AS A CROSS SUPPORT

Railways public transport play important roles in Indonesia in which it becomes one mode of national transportation system with bulk freight characteristics and it contains more advantages compared with other transport modes.
