Not including high-speed rail, or freight, what are some of the steepest cants used for tracks? Doesn't seem to be much on this on the web.

I'm not sure of the exact numbers, but I know that metro systems and light rail often use steeper cants than conventional rail, especially in urban environments where space is limited.

Per Wiki:
As of 2007 the US Federal Railroad Administration regulations limit CANT to 7 in (178 mm) for tilting passenger vehicles, 3 in (76 mm) for conventional vehicles. This FRA regulation is based on AAR standards based on a single study in the 1950s on a rail line in Connecticut.
In Germany, where axle loads are typically lower than those in the USA, tilting trains are allowed to operate with 12 in (305 mm) CANT in some cases.
CANT above 6 in (152 mm) can be considered too uncomfortable for passengers (e.g. things on tables might slide off), except for tilting trains.
