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