£££££,,,,£ ,,,,££,,,,
,£££,,££,, 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! ,££££,,£££
