The "bustitution" policy that replaced rail services with buses also failed. In many cases the replacement bus services were slower and less convenient than the trains they were meant to replace, and so were unpopular. Replacement bus services were often run between the (now disused) station sites (some of which were some distance from the population centres they served), thus losing any potential advantage over the closed rail service. Most replacement bus services lasted less than two years before they were removed due to a lack of patronage, leaving large parts of the country with no public transport.
