On paper, it might seem like 110 and 100 kmph don't make a huge difference, but in reality they do. Even assuming just a 10 hour run at 110 kmph vs 100 kmph, the difference in distance covered is a whooping 100 km. So yes, MPS actually matters. Secondly, Diesels also do the job well. During ALCO era, Bihar Sampark Kranti frequently covered GKP-LKO in 3:30-3:45 hrs with a single WDM-3A/D + 24 overloaded ICF coaches.
please wait...Translate to English110 and 100 kilometers per hour may not look that different on paper, but let me tell you, in real life, it's a big deal. Just imagine, if you travel at 110 kmph for 10 hours instead of 100 kmph, you'd cover a cool 100 kilometers more. So yeah, speed does matter. Also, diesel engines get the job done too. Back in the ALCO era, the Bihar Sampark Kranti train used to zoom from GKP to LKO in just 3 and a half to 3 hours and 45 minutes with just one WDM-3A/D loco and 24 overloaded ICF coaches.
