The number of passengers then hit a first peak at approximately 800 millions in late 80’s. There was a dip again after that, however, it recovered with further increase and ended up at nearly 1100 in 2004/05. Meanwhile, Light rail & metro systems railways have been remaining almost stable between early 60’s and 1980 with the value of around 1 million passangers. After 1980, the quantity of passengers rose till the end, accounting about 200 in 2004/05.
Considering only one category with downward trend, usage of National rail network went up in late 50’s with just under 1100, and then decreased until early 80’s, hitting a low at nearly 600 millions trips. It increased chaotically, accounting just under 1000 in 2004/05.
