CrystalKat is almost right about the ride time...from the time you leave the boarding platform until the lap bars pop open in the unloading station, assuming the ride is operating on interval, is darned close to 2:42. Last time I was up there, I timed the ride interval at 0:40, which is a little slower than I got in the past (which was 0:30) and the ride time for my one ride at 3:12. There was, however, an unspecified delay someplace so we spent a while sitting on the block brake uptrack of the unload station.
Indeed, Disaster Transport is a short ride, but remember that there is a brief delay...about fifteen seconds...on the ready brake before the lift. Then the lift is extremely slow...even though it is only 63 feet to the top, it takes long enough that there are often two cars on the lift at once. Assuming a 0:30 interval, that means the lift takes more than a minute. So you're at a 1:15-1:30 ride time by the time you get to the top of the lift. Bernz says 0:40 from the top of the lift...it's more like a minute (I'll bet CrystalKat knows for sure), but then there is usually a delay on the block brake before unloading as well. So you get to spend a full 2:42 on the ride.
The bobsled coaster at Kings Dominion is completely different from Disaster Transport. Disaster Transport has more in common with the bobsled coasters at The Great Escape and one of the Six Flags parks whose name escapes me at the moment...
