Cogwheel Railway in Buda Hills. If you want to break away from the busy town and the must to see tourist attractions it is also easy in Budapest. Just head to Buda Hills and take some time in green. You should start with the Cogwheel Railway (Fogaskerekű Vasút). It is run by BKV (Budapest Public Transport Co.), so your ticket or day pass will be valid on this too. Its lower end stop is just a couple of stops by tram No. 56 from underground stop "Moszka Tér". The upper end is on Szabadság Hegy/Hill.
