For those who have to go :
1. IIT KGP - Come out from the Pf 1 side of KGP and take Taxi/Auto/Cycle-Rickshaw. There would be plenty in amount but do take care before boarding because there is no prepaid booth or any rules regulations for fare deciding. So confidently negotiate before opting Taxi or Auto.
2. Kalaikunda - Check for any train (MEMU/passenger) for kalaikunda. That would be very much beneficiary. Or else , go towards the Pf number 8 side (the other side of Pf 1) and come out. Turn Left...

and walk bit ahead and turn right on second turn. You will reach Tempo (Tumtum/Vikram) auto stand. They directly go to kalaikunda and charge 30Rs per person. The total distance is 13 km (35-40 minutes journey as part of road before nimpura is under construction) from Kharagpur station. Or else if you are lucky enough then you may even find Airforce bus waiting for passengers to take to kalaikunda. Just show your identity card (Bus facility is only for military persons and their families) and travel without a penny spent for this journey. But do take care , there are 2 huge airforce stations in Kharagpur- Kalaikunda and Salua. So before boarding , so check which station's bus you are boarding.
The whole Kharagpur gives feeling like as if you have came inside a "Very Big" railway establishment with all states of people living together. Here i have seen Odia , bengali , Telugu speaking communities living together very efficiently. Shopkeepers here speak Odia in same fluency as they speak Bengali. Where ever side you go in Kharagpur , you will come across uncountable railway tracks every where. You will be surprised and scratch your head where this track goes or where does this track comes from.
PS: Kalaikunda airforce base in short form is called as KKD among tempo walas.
