I'd have to look it up to get more precise details but essentially back when BART was being built out originally they wanted to build through developed land (could've just been the underground rights). They were able to acquire everything except for one parcel. I'm hazy why eminent domain wasn't used (especially since it's been so wildly abused elsewhere in the country in the subsequent decades), but ultimately BART had to build around this property resulting in an absurdly tight curve. The store is gone but the wye remains as a bottleneck – BART trains have to slow to walking speed (ok ok about 18 mph) to go through it.
