  3. Swiss Railway Switzerland is a very mountainous country and the railways are designed to cope with this terrain. Different systems are used to cope with different gradients. The distance up u divided by the distance across a is called theGRADIENT of the slope. u up a across

  4. Swiss Railway The steepest gradient an ordinary train can cope with is 0.09 In a funicularrailway the car is fixed to a cable which pulls it up the hill. The steepest funicular railway has a gradient of 0.89

  5. Swiss Railway Mountain railways use a rack and pinion system. A toothed wheel runs along a toothed rail. If a single car uses this method the gradient can go up to 0.5 If cars are joined together in a train the maximum gradient it can run on is 0.125

  6. Swiss Railway Phil needs your help! He has dropped the pictures of the railway bridges and cannot remember which is which! It would help if he knew which type of railway used each bridge. You have the pictures. Find the gradient of each railway, correct to two decimal places. Write down which type of railway would be suitable for each one.
