These motor cars were numbered “A-1” and “A-2” and were 55′, 36 passenger motor cars.  The North Coast railroad bought these cars in Mid 1910.  These motor cars were both later sold to the Oregon, Washington Railway and Navigation Company.  A-1 became #600 and A-2 became #601, and later on, the cars were numbered to M-76 (from #600)  and M-77 (from #601.)
