Public transport in communist Poland was horrible because it was severely underfunded. Remember that Poland bankrupted in the 1981 (when the West put sanctions on the country after the Jaruzelski's "coup", and sanctions kiled the economy) the whole decade was kind of surreal in terms of state's lack of funds and decrease of living standards.
The bankrupcy was over foreign debt in foreign currencies, obviously you can't print those. The government borrowed those monies in the first place a decade ago to buy some technologies (patents, licences etc.) from Western companies in an attempt to modernize the economy.
And here we come to the crux of the train issue - elitism. You both find it below your level to use public transport, and you don't want to mix with the 'unwashed masses' - again, doing so would be below your level.
