What is this space is Sayre Yard?

What the space with the star used for something, like a building? Or did something like switch geometry necessitate the curve? Thanks. Always been curious as I've seen it in multiple photos.

A photo that I took from the Lockhart Street Pedestrian Overpass with my Kodak Baby Brownie Special camera in July, 1949, facing in the same direction, reveals what appear to be a line of cabooses on a track in that area.

Intersting. So the caboose track was moved further east. You can see the line of cabooses. When there are no cars around, you can also see the support building and fuel tank.

i've seen an old postcard that shows a view looking west from the area around the station. it looks like there is/was an old "candycane" style water spout in that space. i always wondered why they didn't shift the tracks, once whatever was there was removed, but i guess "if t ain't broke, don't fix it" applies. the hack-track was always north of the jog, in any pics/postcards i've seen.

There is an older thread where this was discussed a while back. Best idea is that these tracks were originally for milk/express car pick-ups as there were crossovers and switches in the depot curve to access them from the east end, and they seem to have disappeared after the end of passenger service. They may have been used as surplus caboose storage tracks for a while but the official caboose track was two tracks over from the east leader. You can see here only the north stub is easily accessible (via the east leader), the south was only accessible from the WB main.
