Lat,Lon,Community,Owner,Bays,Diameter,Table length,Date built,Date demolished,Status,Comments,URL
Lat,Lon - in NAD83 (GPS) decimal degrees format, centered on the turntable. I use ACME Mapper.
Community - the name of the location (e.g. Selkirk)
Owner - Name of the owner (or branch or subsidiary, e.g. RW&O) when it was last used by a railroad
Bays - the total number of bays served by the same turntable
Diameter - Not quite sure what to use here because not every bay was the same length.
Table length - in feet, at least until the US changes to the metric system.
Date built - in mm/dd/yyyy format. If you don't know the day, use mm/yyyy. If you don't know the month, use yyyy.
Date demolished - leave blank if any portion of it still stands, use a question mark if it's been demolished but you don't know the date.
Status should be one of:
- Active - if currently being used by a railroad
- Reuse - if in non-railroad use
- Idle - if it seems to be unused or used for storage
- Ruins - if any portion of the roundhouse is still visible, even just the turntable
- Historic - if nothing remains of the roundhouse, turntable, or pit
URL - if there's a web page with information about the roundhouse (railroad.net URLs preferred!)
If you have to guess at anything, put a question-mark after it.
Here's a few that I know about:
