Certainly true here in Portland, OR.  The oldest sections of the regional light rail system were constructed ca. 1980.  There&#x27;s a project starting next month to replace the track (along SW 1st Ave) which has caused many delays and considered a major hazard to reliability.<p>Rail&#x2F;streetcar public transportation is quite popular in the region and well-used, though it doesn&#x27;t stop auto traffic from being a nightmare with increasing frequency.<p>Edit: spelling.
