I don't even know what stations have them & which ones don't, since I always make sure that I use the bathroom before leaving home. But I think that it's high time that restrooms are being put in stations now!! After all, people DO have to go. It's part of nature. I just remembered that there is one at Ailwife Station, & it's before you pay to enter through the turnstyles.
The only problem is that homeless & drunk folks may go in there for sleeping quarters & may not come out for a while. How is that aleviated? Can't put servelence cameras in there. It would become an invation of privacy, which would then constitute lawsuits.
