The full caption claims the roundhouse to be on Grimes Lane in Bloomington, and that it is now gone and that even the pit is filled in. (Thanks for the correct location Steve.) The BL-2 photo adds builder and date of manufacture... The Album's Director, John Hostetler, is very active in editing the captions as they are very often wrong. I can imagine the info coming with the donation can often be third or fourth hand knowledge or even just guesses. I have had him correct several photo captions and he does a quick job of it.
