They are all trains, however, we do differentiate them by classes - Here it is the Classic 20101 Locomotive
They are trains, they do NOT look alike, they can be differentiated by their classes. In Maximaphily, I am always gearing towards the maximum concordance achievable in realising a maximum card, for trains too, I will try my very best to source for the best match of the class for each of the train for my maximum card. Class 20 Train is a classic Malayan Train , reddish brown finish look with a Head spotlight, had been a popular train series running on the track in the 60s - 80s.
A maximum card realised with a "Class 20 Locomotive" issued on 22.06.2010, FDI cancel @ Seremban.
