£££,£,£,,£ trains are so constructed that they ,££££££,,£
,,,£££££,£ have to follow a set path. this path is ,£,,,,,£,£
£,,£,,,,££ called a "railway", which is comprised £££,,,,£££
,£,££,,,£, of two metal rails, hence its nickname. £,,£,,,£,,
,£££,£,,££ ££,££,,££,
,£,,£££,£, because the low friction between the ,,££,£,£,£
£££,£,,£££ wheels of the train and the rail metal, £,£,££££££
,,,£££,£,, there are limits for how acute a curve ,££££,,,,,
,,,£,,£££, can be, and even more so for how much ££,,,£,,,,
,,,££,£,,£ the ground under the rails can be £,£,,££,,,
,,,£,£££,£ sloped. thus a railway is often not led ££££,£,£,,
,,,£££,,££ on top of hills, rather through them in £,,,£££££,
,,,£,,£,£, tunnels (if they are large), or ,£,,£,,,,£
£,,££,££££ artificial chasms. £££,££,,,£
,£,£,££,,, £,,££,£,,£
££££££,£,, there will be trees on the side of the ,£,£,£££,£
,,,,,,£££, rails, but not too close, or they will ££££££,,££
£,,,,,£,,£ be cut down by the railway janitors. ,,,,,,£,£,
££,,,,££,£ there will be plains, and bodies of ,,,,,,££££
,,£,,,£,££ water. ,,,,,,£,,,
,,££,,£££, ,,,,,,££,,
,,£,£,£,,£ trains go by day and by night. along ,,,,,,£,£,
,,££££££,£ the way, there is information £,,,,,££££
£,£,,,,,££ scattered, often put on top of poles, ££,,,,£,,,
££££,,,,£, to be interpreted by the train drivers. ,,£,,,££,,
£,,,£,,,££ different parts of the railway have £,££,,£,£,
££,,££,,£, different speed limits. ,££,£,££££
,,£,£,£,££ ,£,££££,,,
,,£££££££, sometimes, trains have to stop and wait ,£££,,,£,,
,,£,,,,,,£ for something to happen, far away. this ,£,,£,,££,
,,££,,,,,£ is signaled by red or green lights. ,££,££,£,£
£,£,£,,,,£ ,£,££,££££
,£££££,,,£ ££££££££ ,£££,££,,,
,£,,,,£,,£ ,£,,££,£,,
,££,,,££,£ many people follow the rails by foot. ,££,£,£££,
,£,£,,£,££ often this proves to be the shorter ,£,££££,,£
£££££,£££, path between two points. however this ££££,,,£,£
,,,,,££,,£ is frowned upon, and very impolite ,,,,£,,£££
£,,,,£,£,£ toward the train drivers! ,,,,££,£,,
