They need roofs for schools and colleges when there is no summer uplift. They can just about get away with moving singles around post Easter, due to reduced school commitments. But they need them roofed for September!
Surely the peak requirement for vehicles is May - mid July, Open toppers in use, schools/colleges open, foreign language students in Bournemouth. (this explains why they have Manchester Scania 'deckers on hire at the moment).
The schools/colleges start again in September (when open tops still operating).
Historically the argument has always been, do you: -
1. Have a fleet of older (permanent) open toppers used from May - September and parked up de-licensed over the winter
2. Have a modern fleet of convertibles which can be used as closed toppers for the rest of the year.
Go-South Coast have followed both policies, presumably they do so for both pragmatic and cost reasons.
Some of the open tops are getting on age wise.
The 2 ex Yellowbus Volvos may last a few years yet as they only see use in the summer, ditto the 2 IOW Volvos & solitary Scania conversions.
The Volvo convertibles (54/05 reg) now nearing 23 years old see use 12 months of the year.
I have no knowledge/insight into the mechanical/bodywork conditions of the various vehicles, they may soldier on for a few years yet?
The debate seems to be around whether replacements are new convertibles (big cap-ex) or older conversions, parked up out of use for 7 months of the year.
I don't pretend to know the depot parking situation on the IOW, presumably the vehicles were parked 'under cover' at Newport?
Would be interested to know more, is Ryde still used as a parking area? Also Whitmore road?
