A very large application of Motter Tektura on the side of Speno’s locomotives. Speno is a rail service company specializing in grinding, measuring, and inspection of rail tracks. Looking at other photos of Speno equipment, the earliest occurrence of this logo is from 1982. Don Ross has more information about the company and their machinery. Speno is still in business, but they don’t use Motter Tektura anymore, which is a shame.
