Yes an interesting situation here.
I live Thornton Cleveleys and from 2004 to 2010 was involved in rail replacement with first Fraser Eagle and then with First Rail Replacement...This means I have knowledge of the problems etc that possibly will happen.
At the Preston end the yard in my day did not have the carbuncle in the way,that is the new whatever that now blocks off half the short stay ,causing in my opinion at certain times of day chaos,as there are up to 10 buses an hour each way,to greet ,unload and reload ...It is going to be interesting !...At Blackpool North,there maybe issues,as don't forget,the station and platforms are being demolished and then rebuilt....Must say I can't see deliveries going onto site via the end buses will be operating...Blackpool South no issues there.
What is different is that one bus operator/supplier is doing the job,Blackpool Transport,with brand new buses....I am wondering if Northern Rail the TOC on the line,will use their own people that do co-ordination or surplus Northern Rail staff will be involved...This will only apply at Blackpool North,other locations will need co-ordinators...Frankly after a week or so,actual mechanics of job will be not an issue,the big issue is checking tickets at B NTH...
Regards timings,they will get altered if found to be impossible,from feedback Blackpool Transport.....
One thing to note is that period of block is with exception of half term the quietest time on the line for passengers.
