Difference between LRT and MRT

I do not know how many times I have experienced riding in LRT but I think it is more or less three. The first one was when we bought clothes because I was a CAT officer before in highschool, the second time was just recently (this month of September, 2011) and I've forgotten the third. :P While in MRT, I rarely ride in it even though it is near to my current workplace.

What differences do they have? Of course, the beginning letter of the word and what it means (Light Rail Transit for LRT and Metro Rail Transit for MRT). The LRT is more primitive and long existed than MRT. Therefore it is old and lying along the Manila area while MRT is the new version of it that lies on Edsa. LRT stations are closed to one another while in MRT, stations are far from each other (based on my experience and observation).. The two are meet at the Taft station (Pasay Rotonda LRT-MRT). There I found out that the two are not rivals when it comes to passengers because they have their destination and place occupied. Due to being curious, I got to know the things I should know before, not when I got a job. Thanks to my brother. Now, I have heard stuff as LRT 2 and I do not even know where it is lying. I don't need to worry, because no secrets stay hidden forever.

What about you, are you aware on their differences?
