Potters Bar accident, Feb 1946 - A double V2 incident?

[0-6-0]

I purchased a copy of The Power of the Austerities by Gavin Morrison in OPC's Power Series from Nick Tozer over in Huddersfield yesterday.
Browsing thru it last night I noticed on page 39 at the top was a picture of 2-8-0 Austerity 78710/3174/63174/90495 hauling an N2 0-6-2T 2679 and an unidentified V2 sans it's tender. Reportedly following an accident in the London area.
Well doing a bit of research on t'internet I was able to find out this was the accident in Potters Bar on February 10th, 1946.
Reading the Ministry of War Transport report into the incident I found out that two V2s were involved, 4833 & 4876; so anyone like to hazard a guess as to which of these is the one with-out it's tender being hauled by the Austerity?
Also where might they have been going?
Finally, is this the only case of two locomotives from the same class being involved in an accident together?

Regarding Mr. Tozer's establishment, leave all funding at home if you venture there; I went over to collect two books, came away with another two and I'm now drawing up my next shopping list!

Certainly not the sole example of two locos of the same class in an accident. At Hull Paragon in 1927 it was contrived that two ex-NER 4-4-0s (LNER D17 I believe) were neatly run head on into each other. The GCR managed the wreck of a pair of what became LNER D7 while double heading. The Norton Fitzwarren accident involved trains both hauled by King class locomotives, although of course the one on the through line was untouched, and the terrible Harrow accident had a Duchess and a 'nearly Duchess' ex-Turbomotive conversion into each other.

Those are just a few I recall. Common locomotive classes in fairly intensive usage in any given area are likely to have had unplanned encounters, many fortunately too slight to have gained more than technical notice.

Ah well not as unusual as I thought but many thanks for your comments Hatfield Shed.
HAT or 34C?
