ANW and ABW double decker influx - where next?
So with the influx of double deckers over the past few years the question now is - does it continue or have we seen the last of it? Personally I don't think we have - there's a good few routes left in the North West that are desperately under capacity - with the 7, 8/9 and 53 being the priorities for me

2014:
12 - Rhyl-Llandudno (converted from single deck; new Sapphire stock)
86/86A - Liverpool-Garston/Liverpool JLA (stock upgrade)
375/385 - Southport-Wigan (stock upgrade)

2015:
10/10A - Liverpool-St Helens (converted from single deck; new stock)
10/10A - Chester-Connah's Quay (converted from single deck; new Sapphire stock)
10B - Liverpool-Huyton Elizabeth Road (converted from single deck; new stock)
12/13 - Liverpool-Stockbridge Village (converted from single deck; new stock)
15 - Liverpool-Huyton Bus Station (converted from single deck; new stock)
52/52A - Liverpool-Netherton (converted from single deck; new stock)
75 - Liverpool-Halewood (converted from single deck; new stock)

2017:
1 - Wrexham-Chester (stock upgrade)
14 - Liverpool-Croxteth Willow Way (converted from single deck; new stock)
18 - Liverpool-Croxteth Park (converted from single deck; new stock)
51/X51 - Rhyl-Denbigh (converted from single deck; cascaded stock)
55 - Liverpool-Old Roan (converted from single deck; new stock)
79/79D - Liverpool-Halewood (stock upgrade)
89 - St Helens-Liverpool JLA (converted from single deck; cascaded stock)

In summary:
ANW: Bootle (21), Green Lane (71), Southport (9), Speke (57) and St Helens (26)
ABW: Chester (9), Rhyl (20) and Wrexham (13)

Does anyone have any ideas of what other Arriva North West/Arriva Buses Wales routes they think need upgrading to double deck?
