Taking a staggering 13 hours and 20 minutes, this epic course features 35 stops (36 if you count the one you board at) and a grand total of two hours in total stood still, waiting for passengers to embark and disembark at each station along the way.
Such a change would mean passengers wanting to travel the length of the UK would have to make a transfer (most likely to be in Edinburgh Waverley - Scotland's biggest railway station).
UK's longest 785-mile train ride may still continue in 2025 despite axing fears It could soon be the end of a railway era - or perhaps not...
But, speaking to the Mirror, a spokesperson for Cross Country did not confirm or deny whether the non-stop route would be axed, pointing out that its future timetable remains a draft.
As previously reported, this journey is ideal for those wanting to admire Britain's unappreciated beauty from the comfort of your own seat: from the sandy beaches of Montrose to the AONB of Alnmouth - all the way down to the tourist-crazy town of St Austell.
