very newbie question abt tracks buildup

[teckkk]

hi, can anybody explain the rationale behind all the extensive railway networks?

what purpose do they serve and if i were to learn how to build them, how and where should i start? is there any guide for them?

The main purpose is for enjoyment rather than 'making money' (in game).

If you want to learn read the wiki:

Look in the column to the right under the railways tab to see pages on various things like station layouts and signaling.
