This train is more of a Mumbai-Solapur Daytime intercity connectivity , only name change at PUNE.
Thats why they send a Direct SINGLE Diesel Dedicated ALCO from CSTM in the morning , which again reaches CSTM in the night time.
Majority of times it gets Diesel ALCO.
Actually if you check the Arrivals at PUNE , then you can see that this train...
more... in some days arrives even at 09:20 am also , Thus means its not 100% confirm that this train will reach PUNE at exact 09:08 am. Thats why CR doesn't takes risks with Loco change overs. Some days it may reach PUNE on time , then 20 minutes are enough to do Loco Change , but some days it gets 10-15 minutes delayed , then if loco changing is done , it forward journey will get affected , pus along with this return SOLPAUR-PUNE-MUMBAI journey will also get delayed which is NOT AT ALL ACCEPTABLE considering the TYPE of working class people travel in this train , specially between PUNE-MUMBAI.
