I am intrigued by this, and as a user of trains I hope it provides a better service to MK Central than the MK1. Of late, for trips on the west coast line I have generally used the F70/77 to get to Leighton Buzzard station in preference as they are more reliable and quicker. The MK1 is great for those who want to get to the warehouses around Kingston, but not so good if you don't appreciate the faffing around! I'd also add that most bus services centred on Luton seem to have no shortage of users - I suspect that the town provides a significant part of the workforce for quite a wide area!
Yeah, I have travelled on the MK1 from where I live near Bedford to Milton Keynes which took nearly 2 hours each way, although long and slow, was quite fun, and a bargain at £2. Like you say, the MK1 is great for those who want to go to the warehouses but I wouldn't get on it to MK as although it's supposed to be quicker as it goes on the motorway, it never is as there's always traffic, roadworks, or an accident on the M1.
Yes, Luton does provide a large workforce for the warehouses served by the MK1. Every time I use the bus coming home from Luton, including today, there are always so many workers going to the B&M Warehouse in Wixams. I also see a lot of workers heading to the Amazon warehouse and the other warehouses around Kingston.
Personally, as a daily user of the MK1, and I have been saying this since it commenced, Stagecoach is better off running it from Bedford to Luton Airport and then back, especially as the M1 always causes delays during rush hour. People, especially the elderly who rely on the bus timetable as they don't use bustimes.org to track the live location of the bus, are sitting at bus stops between Luton and Bedford waiting for over an hour because the bus is late through no fault of its own. Whilst Stagecoach has given it a few timetable improvements lately, they aren't that much of a help. For example, it's given a 6-minute layover at Luton Station heading towards Bedford, but today the bus I got was over 20 minutes late, completely defeating the object of a 6-minute layover. Hopefully, Arriva's new X1 service will speed things up to Milton Keynes as long as it doesn't go up the M1. Then Stagecoach will hopefully curtail the MK1 back to the Airport and change it back to the 81 as it will improve punctuality.
I feel like I have spoken about Stagecoach way too much as this is an Arriva thread, so I will end this post by saying that I am looking forward to seeing if the X1 will be a faster way of getting from Luton to Milton Keynes.
Just catching up with this thread, but following what others have said, it is good to see double deckers on the 321. I was on it last Saturday and they were a welcome sight. However, I was slightly confused by the service as it appeared that it was running at half-hourly intervals as per the timetable, but with another bus running a few minutes ahead (or behind). I'm curious as to what was happening.
This is probably due to the roadworks which I believe are in the Harpenden and St Albans areas. Also, the fact that the 321 is such a busy route on weekends probably doesn't help with punctuality either as the connections are better during weekdays between Luton and St Albans when the 721 is running.
