First installation of 1926 at Beech, Mich., 12 mi. from Detroit, and of changes incorporated in new installation; experience with these two experimental sections lead to conclusion that advantages, tangible and intangible, of permanent roadbed would appear to justify amply its additional cost of $13,000 to $18,000 per mile.
