When I first installed Rush Hour a while back, I had a fairly annoying issue with the El Rail -- I would lay some rail, and try to place a station, and be told the tiles were already occupied. I didn't have any mods (at the time), and I had the game patched to the latest version. It was a stumper. I tried re-installing, and various other things suggested, but I didn't get anywhere. This was happening even when I'd run the tutorial, and try to place the station where suggested by the game -- it'd bulldoze the rail where the station was to be, and plop the station down, but try as I might, I was unable to get the rails to connect. So I thought, Maybe it's one of those weird graphical bugs... and turned on some cheets, built a little residential area, laid some el, and some farmland a ways off, and tried to connect the two with the el -- nothing. I ran a road out, and *blam* it worked. Until I turned Hardware Acceleration on in the graphics options. It had been reset when I installed Rush Hour (ATI Radeon 9700 Pro), and while the rail I HAD lain was still dysfunctional, all future rail laid worked fine. I decided it was time for a test. I laid some good rail in my little test city, and I zoned out some more farmland in a different direction, laid down stations, and turned the acceleration off, saved the game, restarted, and tried to lay the rail -- worked fine. They connected. I figured, What the heck! and tried to add on to my now-working rail lines, nada. What I gather, then, is when you have graphical acceleration turned off, plopping down el rail stations is somehow bugged. I have NO idea why, how, or even what. But there it is, and how I fixed it.
