ever since germany privatised rail (and post) while remaining mayority shareholder it has become ultra shit.

quality and reliability has gone down extremely over the years. efforts to mitigate the damage done thanks to neglect probably cost much more than proper maintenence would have cost them. those efforts are paid for by the state ofc.

deutsche bahn is so unreliable, neighbouring states have to cope with them disrupting their own schedules. if anything its reliably unreliable

but you already have a shitty underfunded rail system, so not much change there. the post office on the other hand will be heavily noticeable
