Surprisingly enough, according to a survey made by World Economic Forum in 2013, Malaysia has better railroad infrastructure than Denmark and Sweden.
Malaysia ranks 17, and Denmark is ranked 19 and Sweden 21.
While Finland is in the top together with Singapore, Norway has long had some of the slowest roads in Europe and the traffic flows worse than in countries like Sri Lanka and India.
In other parameters the Scandinavian countries ranks higher – e.g. port infrastructure, where Norway moves up to a position 25.
