The newly repowered Class W2a 715 Diesel Hydraulic locomotive rolled out from Ratmalana railway workshops on 6th August 2015.
This locomotive is completely different from the W2 class. Class W locomotives had a Paxman Ventura V16 diesel engine (prime mover) while the W2a has been fitted with a Paxman Valenta V12 engine. Other than that the controlling system of W2a is a much more advanced electric control system than the traditional control system of Class W2.
