Depending on the day of the week, the Stagecoach Yorkshire X17 runs a grand distance of 47.12 miles between Barnsley and Wirksworth.
Now here's the problem with this... The allocated Enviro400EVs are currently banned from any graphs containing X17 trips. BUT... it's not for battery capacity concerns because of the distance. They are experiencing a manner of failures with their brakes, paired with braking upon reaching 48mph rather than just holding that speed. These issues are causing problems on the motorway and bypass sections, as well as Slack Hill. Oh the joys of ADL...
Might I add that our Yutong single decks are handling this route fine when allocated
