I thought this post was going to be called “Tender final details” until I looked at the photos. Don’t the side sills look plain? That’s what I thought too, and it sent me scurrying to the reference material. So, there’ll be another post tomorrow. It turns out the handrails and lift bars are only the penultimate details.
The coupler lift bars look like they are very far in, but they’re supported by a good photo of sister engine #624’s backside. With the boiler stays, I discovered that a plastic nut-bolt-washer casting actually adds a surprising amount of strength to what ought to be a very weak joint. So, I fixed the cut lever stanchions in place with some too.
