For travelling from mumbai to bangalore use this train and transfer to SBC-UBL Jan shatabdi onwards from UBL towards SBC if tickets not there in chalukya. Its a good fast chain with nice time for food at UBL. Prefer it over direct trains like Udyan and 11013 in the LTT-SBC section if tickets not obtained in chalukya.
Works well in both directions as well. In fact chalukya is empty many times in the UBL-YPR sector (seats available in current) so if you prefer you can catch that train as well from UBL!
