There are a lot of comments on here that appear to be criticising the company for plans that have been entirely invented on here as if they are official statements, the only people who know the strategic plans for Baslow are the directors of the company and as far as I know they aren't talking to anyone else about it.
There have been a number of suggestions/questions being thrown around and whilst I don't know the companies view of them I can make a couple of stabs at probably reasonings as someone with experience in this type of decision making process:
1. Why not run them from Dove Holes like the Ashbourne contracts?
I can see two possible reasonings here. Ashbourne is much closer, in driving time at least, to Dove Holes than Matlock is - most operators will have a maximum distance from the depot for the closest point on a route to make it viable (driver swaps and dead time) which will be different to furthest from the depot a service reaches, Ashbourne is clearly within it but Matlock probably isn't and I believe one of the routes in this package is Nether Heage - Belper - Alfreton which is even further away. Baslow to Alfreton & Belper is fairly similar to Dove Holes to Ashbourne in travel time in that sense. I'm jot sure if High Peak have ever tried to bid for work in the Matlock area before but they haven't won anything that far away.
Secondly possible Dove Holes is struggling for capacity, not just vehicle parking but driver availability (the proximity of Manchester & the Bee Network may be unbalancing the driver supply in the area at the moment and until it settles down it may cause problems).
2. Why not use the TrentBarton Garage in Matlock?
As far as I can tell because there isn't one, they may park some buses in the yard of the old depot which is now an MoT centre but they don't have a garage just an outstation so it doesn't have the facilities to provide the support that may be needed by High Peak. That will work for TB, it can be easily supported by Belper distance wise but it is a little different supporting such from Dove Holes. Also from previous public statements and actions TrentBarton seem quite keen to keep themselves seperate from other businesses, even within the Wellglade group - the TransPeak buses in Derby are parked in the Notts & Derby section of the depot not the TB one and when there are issues it is N&D who provide the support. There is also the issue of whether Wellglade would agree to parking buses in their depots to operate contracts they could have won by their own 100% business to run from the same site.
3. Why not pick a different depot site in a place I think is better potential (like Chesterfield)?
Is there somewhere better available? Do you know of a suitable site, already set up to take the specialist infrastructure needed for a depot (like fuel tanks), with existing use permissions ready to be activated in little more than a month? I don't and I assume High Peak don't but may well have had an existing arrangement ready to go dating back to when Hulleys collapsed and they would have been identifying sites to cover the work if they had managed to gain it which they could bring forward.
The value of a depot is only if it is in use, the longer it stays unused the harder it will be to re-activate particularly when it is like Baslow and surrounded by houses as residents will get used to no bus depot and then object if someone tries to start operating again after a year even if the site had been so for decades before. People are assuming the depot was picked after the contracts were gained, it is just as possible that the contracts were only bid for because the depot was available making operation viable.
There is also quite a bit of speculation about what the future plans are for the site that justifies the opening of it, whilst this overstates the level of strategic planning that probably exists (they have an available site and available contracts which are close enough to be a viable bid) I can think up several possible future ideas that may influence the idea that a depot in that area is attractive:
a. South Yorkshire Franchising. There are two cross boundary services that are operated by South Yorkshire depots that TSY may not want to take on. The 218 operated by TM from Halfway & the 272 part-operated by First. The former effectively passes the depot site whilst the later will be Sheffield ended journeys for which Baslow is slightly more convenient to cover than Dove Holes and at least one of those vehicle workings are unlikely to be able to be switched to Castleton ended due to a large school flow into Hope (it is also complicated for Dove Holes to maintain deckers, it has only had a single vehicle for a short period of time in recent imes, but I assume Baslow could since Hulleys did).
b. Reducing pressure on Dove Holes. Ashbourne is not much different in travel time to Baslow as Dove Holes so moving the 113 & 114 could reduce pressures on Dove Holes without adding massive extra staff costs.
c. Further tendered opportunities. The other former Hulleys routes may still have a year on their contracts but I refer you to my comment about a depot site only really being valuable if it is operating so having something up and running means it may allow High Peak to be price competitive with Andrews. There are also other contracts in the Alfreton, Chesterfield & Matlock areas generally that this depot site opens up as feasible which previously wouldn't have been due to the distance from Dove Holes.
d. Other commercial opportunities. I'm sure many of us could think of route links that don't exist that we think should, or improved service levels in this area that such extra depot capacity could allow. Just improving the top end of the TP where so much demand is could be assisted with a depot at the Bakewell/Matlock end though I doubt High Peak would want to move the core route of one of their high profile brands out of their main depot where it can be managed more closely.
Baslow isn't a big site so only one or two of these would get the depot to the sort of capacity that will leave the site at a comfortable capacity (around 15 vehicles, the reported work is unlikely to require more than 6 vehicles to be based there initially).
