Graham, thank you for the update!  Understanding the cost to build a proxy box ($150-170USD) for 27 cars, I’m fine with adding a few bucks to help with the cost of a 40 car box.

Many thanks Tony, I wil be ok for now. The existing ones will now need complete replacement. But I would expect to get 2 proxy series out of them when done. I think actually the current box did protect most of the cars quite well, the force of the impact to burst through the outer rigid foam layers would have probably demolished most of the cars into pieces if not for the internal boxes. But I think they could be improved.
