This is just my opinion. I view relations as data that cannot be easily inferred from other data in the OSM database. The MRT3 ways are connected end-to-end and have the same tags save for the layer, bridge, and tunnel tags, so it can be easily inferred that they constitute one railway. Therefore, I don't think an explicit relation is needed especially since relations are harder to edit. For example, you cannot just merge two of the ways in this relation into 1 way. You have to remove both of them from the relation first, do the merge, then add the combined way back into the relation.<br>
<br>But, I'd appreciate any input if my understanding of relations is wrong.<br><br><br><div class="gmail_quote">On Tue, Apr 7, 2009 at 11:21 AM, ian lopez <span dir="ltr"><<a href="mailto:ian_lopez_1115@yahoo.com">ian_lopez_1115@yahoo.com</a>></span> wrote:<br>

Before, the ways representing the MRT3 are disconected due to the "layers". Recently, I created a <a href="http://www.openstreetmap.org/browse/relation/109159" target="_blank">relation</a> that connected the said train line.<br>
My question: Can we apply this to LRT1 & LRT2 (and possibly PNR lines in the near future)?<br></td></tr></tbody></table><br>
