Just out of curiosity why do parcel trains have blue hazard lights?
Is it so once upon a time the box could identify them easier?
No parcel trains have run since about 1990.

Sorry .... I don't understand your question.
No parcel trains have run since about 1990. There are the Royal Mail class 325 mail trains running, but these carry letter post, not parcels. A test service was run for TNT into Euston a couple of years ago but nothing has come of that test yet.
325s are the only things running around with blue bodyside lights. The rulebook used to say that no action is required by drivers and signallers if such a train is observed with those bodyside lights illuminated (for the orange equivalent 'hazard lights' that are on passenger stock, signallers and drivers are required to take action if a train is observed passing with these illuminated).
I thought it was because movement had been detected inside the van rather than interlock issues hence the blue colour rather than orange and lack of need for action.
From the occasions that I have been down to Willesden and Dallam PRDC, it would appear that about 75% of the load are Amazon parcels and packets.

Would plug style doors be more secure for 325s whenever they get a mojor overhaul?
Are any NKAs still in use or have they all been scrapped (or sent to scrap)?

I think they have all been scrapped. There are a couple (or were a couple) slowly reverting to nature in the sidings just outside the PRDC at Willesden, along with a couple of PCVs. There were also a number of NBA (?) 'Super BGs' at Crewe, but they disappeared last year.
During the Xmas period last year (and the year before I think), there were a couple of loco hauled parcels trains to supplement the 325 services, but they were formed of Cargowaggons and a class 90 as opposed to dedicated parcels stock.
Iam not 100% on this, but I think WCRC purchased quite a number of Ex RES NKA/NBA/PCVs last year, so perhaps these are still at Carnforth?
