Due to line congestion problems, platform availability issues, loco movement to/from Mumbai/Daund end of Pune Station, lots of shunting activities going on (like rake stabling, taking empty rakes to washing lines), movement of goods using through down/up lines to/from GIT Yard towards Lonavala, etc, and similar other reasons (if any), PUNE Operations has strictly said NO to any D to E or E to D Loco Change at Pune (other than those previously mentioned existing loco changes). Due to this, many trains are running DUW (Diesel Under Wires) from CSTM/LTT to Pune! Besides those CR/SCR/SR Trains, other SWR/SCR Trains like Bangalore-Ajmer/Jodhpur/Gandhidham Group, SC-RJT Exp, CCT-MLY Exp, MAS-ADI Exp, Vivek Exp, etc are also running DUW in the entire Pune-Ahmedabad Double Electrified AC Traction Route!
