Bill, the original line came up from Colton along 8th, crossed over to Mt. Vernon and then turned
on 3rd Street(was that later Rialto Blvd?) About where the line turned south toward the Redlands
trackage (and Mill St), it also turned north along D Street and then Highland and then of course
as you mentioned Mountain View. You could tell where the line went off the street and onto the
private ROW headed south that there was also the remnants of the line that turned north, is this
the line you mean??
