The "Big Chuffer" is the biggest train thus far in DU, and the most powerful. Also the only product in RMC and RCC. Horsepower: ~12,800 (Rough calculations) :0 Speed: Only engine max of 87MPH (I'm horrible at judging speeds, correct me if I'm wrong.) Weight: 2000 tons. To slow down, electromagnetic clamp type brakes are activated by a lever. Gauge: Triple.
I'd like to credit Animagraffs on Youtube for an amazing video on how the Union pacific 4014 "Big Boy" works. Press space. I'd like to thank @flakpanzetea100 for his train nerd seal of approval.
