Premise: The Port Klang line runs east to west, from Batu Caves to Port Klang. Batu Caves is less than 15km / 10mi from home, so a train ride from there doesn’t make sense. Port Klang, at 50km / 31mi away, is further enough away to make a one-way ride to that station seem worth it
Statement: Port Klang, at 50km / 31mi away, is far enough away to make a one-way ride to that station seem worth it
