Colas 37s make their mark as RHTT season begins

摘要

The annual rail head treatment train season is well underway on many diagrams from bases across the country. The Colas Rail diagram out of Kings Norton, Birmingham, has been working with two Class 37s. In a situation that is becoming all the more common, Nos. 37219 and 37175 have been bought from preservation,tefurbished and reliveried (in this case in Colas branding) and returned to the main line. The indications are that because of stringent EL) emission rules, effective from the end of this year, more preserved and stored locos will return to the main line, the cost being between a quarter and a third the price of a new loco. A further two Class 37s-Nos. 37116 and 37421-are being prepared at Washwood Heath Works for Colas.
