[not allowed]opher, that was the wooden roundhouse they built at Hillside Drive (kind of middle of McDoel yard on the East side, across from the dispatchers/yard office). It burned in 1908, and that's when the brick one we all remember was built farther south down in the yards. / Ron
PS, they never had a "roundhouse" downtown. All they had downtown were square engine houses with the tracks into them leading off a Sellars turntable. See Joe Land's overlay.
