1.The diesel might be smoking because its idling without crew(tough this is a possibility ,present day energy conserving procedures dont favour this).

2.Yes if the second WAG-7 failed,they must have attached the shakti to help this loaded(?) rake climb the gradient(?).In this case,Shakti driver will apply traction as per lead WAG-7 driver instructions while the driver in lead WAG-7 will take care of braking when required and traction.

3.Even shunting rules require the pilot to be in that cab which offers him the best visibility.If shakti alone is applying power,point 2 is valid except that the lead WAG-7 driver wont(actually he cant)apply traction power.

More discussions if any,we will do it in the main list.I can see danger signal coming !!

As Ashwanth says, if an electric cannot be MUED to a diesel, then why was the 'Shakti' smoking?
could the lead electric and the 'Shakti' be both live (but not MUED) or could only the 'Shakti' be live?

1.An electric loco cannot be mu'ed to a diesel.
2.The two WAG-7 locos might be mu'ed but the driver in the leading cab of leading WAG-7 can control the panto of trailing WAG-7(May the rake is empty or the train is descending a down gradient).
3.WAG-7 can be mu'ed to WAG5HA.
4.Yes if I have a trio of WAG5HAS,I can MU all three and then shut down the middle loco if I want.The first and third will still cooperate.

I am not sure which one was the lead loco, Kazipet or Lallaguda. But yes, i too have the same question as Aseem, can the first and thirl loco be MUED despite a dead middle loco.?

can leading Lallguda loco be mued to Katni loco considering the one in between is dead? If so, then can a dead loco lead mued live locos?

Looks to me that the KZJ WAG 7 is dead since the panto is down.
