Have to admit to having a soft spot for the 185's from years of riding up and down the TPE route, I do miss the 158's but they were woefully inadequate for the TPE route. Mark 4 stock on the ECML have been wonderful and still look decent from a passenger point of view, not sure what they're like maintenance wise but the new 800's are a step up - and will eat up more passengers which is the aim of the game after all.
