Actually, a premetro is an LRT system that runs underground in the city centre like a metro, and then runs above ground outside the centre. An example of this is the Edmonton LRT.
The Skytrain and similar systems is normally referred to as "light metro". A light metro may have not have capacity any greater than a robust LRT system. But the LRT system achieves the capacity with longer trains sometimes 100m or longer, while a light metro achieves it with extremely intense frequency. Automated light metros can have trains as frequently as less than every minute and a half (over 40 trains per hour). A light rail line isn't capable of this intensity due to level crossings.
