Hi TimboM,
I am judging that those 20 that DBC listed up for grabs last year have been taken for scrap/reuse? As I cannot find any new information on them. However as I mentioned last year, albeit a pipe-dream. I would love to preserve one of the Class 60's and have it as static display piece

. But when the time comes, I think the super-tugs may well be in line for "active" preservation on heritage lines for working with old BR stock on many heritage railways such as GCR, MNR, NVR etc.
Just my personaly opinion and nothing more. I think 60100 should not be overlooked by the NRM because it was the very last British-made Diesel Locomotive to ever exist and that has given 60100 some legacy grounds for preservation anywhere. If the NRM cannot take it, then perhaps one the Railroad Museums in the United States could take it as they have an A4 over there numbered as 60008. Heck perhaps they could even name 60100 as Donald J Trump to justify its preservation and give that Class 60 a secure future

.
However moving on and being logical. Assuming that some of the other rough-edged Class 60's could have a use on railway sites as if the guts was all taken out. There could be an idea to build a coffee shop in one where the engine room is

. Nothing like a cuppa and some cake inside a piece of British-history and make a profit from the punters too!
