I've done a lot of research on this because I was going to put it on my truck, but I decided not. I planed on installing it only because people seem to enjoy cutting me off, but it's not a good idea for city use. When I buy an RV a few years down the line, it will definitely be installed (highway use). You can buy imitation train horns, but you may not get the authentic train sound. Maybe closer to a big rig sound. Buy a metal horn and not plastic. Plastic will sound ultra cheesy. These horns use a 1/4" air hose line and take about 80 - 100 psi to blow. The tank can be relatively small, 2 to 8 gallons.
If you want to install a real train horn, forget about it. They are too big for the V engine compartment and probably won't fit under the car. You'd probably be able to install them on the roof. You can find real horns for sale, but it's pricey ($500 - $1500 on the cheap). These are the true big boys. The pressure to blow an real horn is actually pretty low, just 125 psi. You'll need a 1/2" air hose so you'll also need a huge tank, at least 20 gallons to get a little toot.
Surprisingly, very surprisingly actually, train horn aren't illegal to install on cars Although it would be illegal to blow in most cases. The decibel limit for horns in most cites range between 90-125. Most train horns range between 130-150. So it would be illegal to blow it. Even if it is legal to blow it where you live there's still a good chance you'll fall into the same category as those who go down the street honking the horn, excessive noise. Using it to play pranks, or just to use it would be stupid, immature, and illegal. There's nothing like blowing your horn, scarring some old lady who has a heart attack and the courts finding you responsible for her death. Using it for valid emergencies or just blowing in an empty field is just fine.
