Re. Great Western Express, services run #1, 1C02, Class 43 HST power....Operating at 120 mph should give a closure speed of 2 miles per minute, or 200 kph=2 kpm. On the long 30+ mile run, distance counter does NOT appear to be counting down at the appropriate rate. I ignored acceleration rate, had train running at exactly 120mph, and noted closing speed, it was incorrect! Anyone else see similar discrepancy? Patch in the near future?
