Yesterday (and past days) I was checking Altoona in Google maps and I took a set of pics about the turntables in the area (so how it looks today).
I believe there were five (maybe six) turntables in Altoona in 1950s. Some like the cars shop was already built in 1895.
1- Juniata shops (see 3rd picture)
2- Cars shops (see 2nd pic)
3- Machine Shops located in front of the passengers station (possibly 1st pic). Seeing the schematics above, it seems there were 2 roundhouses in this area.
4- The fourth is also included in HC route. It is located beyond the passenger station at the exit of Altoona before the curves that take the tracks to the Horseshoe Curve.
However I find comparing both the route (Altoona) and Google maps, that the tracks beyond the passenger station (today Amtrak) are much longer than the reality, not just comparing with the station itself but with Altoona´s Cathedral of the Blessed Sacrament.
I don´t know exactly what was that turntable for (there is no track of it in Google maps)
5- This turntable should be one serving East Altoona Engine house, shown in the graphics provided by The Old Dessauer.
This is the cars shop roundhouse how it looked in 1895:
