I don't know the proper reason but according to me swr has not given kjm wap7 link because kjm wap7 pulls very few trains which are all normal type and not very prioritised trains only ksk and shatabdi are a bit prioritised and moreover all the trains of kjm based wap7 run in a conserved route and not very long route. Kk is often seen with many wap7 because I think it mostly runs with locos which is nearby it's route such as ajni,bsl,et,tkd,brc etc.obviously it's just my opinion but I've seen kk express with kjm wap7 almost 3 times.
please wait...Translate to EnglishI dunno the exact reason, but in my opinion, swr hasn't given kjm wap7 link to kk express 'coz kjm wap7 ain't used much for pullin' trains. They only use 'em for regular old trains, not the fancy ones like ksk and shatabdi. Plus, all the kjm wap7 trains stick to a short route, not too long and fancy. On the other hand, I often see kk express with many wap7 locos 'coz they use the ones that are close to its route like ajni, bsl, et, tkd, brc, and so on. But hey, that's just my two cents, ya know? I've actually seen kk express with kjm wap7, like, three times!
