So sad to see an enormous site, once of such great importance, now reduced to nothing. I have a feeling that all too soon it will be bulldozed. What is the facility across those NS tracks? Is it railroad related? Or an industry? B&LE papers in my collection: https://www.train-orders.com/TOUR/B/BLE/BLE.html
that was really cool video. i enjoyed that a lot. Thank You for posting it. I have never seen a yard where the trains slide side ways to each of those doors very cool.
It's called a "transfer table". They were fairly common at one time. Mostly at major shop facilities. Milwaukee Road had one at their Tacoma, Washington site and also at Miles City, Montana. The latter is still in use today, owned by a rail car repair/rebuild company. Montana Rail Link has one in use at Livingston, Montana.
You'd think a railcar rebuilder company would buy up a sight like this-it's already set-up for what your doing.
That would be perfect for the Age of Steam or Steamtown.... As for transfer tables, the Orange Empire Railway Museum has had the old Pacific Electric Torrance Shops table for decades. Unfortunately, they never dug a pit for it, so it is just a table.
The California State Railroad Museum has a transfer table in the old Sacramento Locomotive works. It still works and they regularly use it.
There is also a fully working (and actively used!) roundhouse and turntable in Jamestown CA (associated with the CA State Railroad Museum in Sacramento).
