Yeah just get some speed, and try to land further down on the rail while looking at the end of it. Don't worry too much about catching your tips. Just be patient, and turn your legs after you're above the rail.
I've personally never understood the point of urban-style rails in the terrain park. It literally just wastes the first 5 feet of rail, because you have to take speed into it to stay balanced, so the rail has to be at least 30 ft to actually have enough time on it to do tricks. Urban setups are for urban environments, where you don't have enough space to get a good set-up or in run.
If I were to design a park, it would have a nice 3 foot gap between every rail and the lip, so you could get onto the beginning of the rail with speed, and ride the whole thing, instead of barely being able to tap the end.
