Service

This train and Chennai Central–Mysuru Shatabdi Express are two fastest trains on the KSR Bengaluru–Chennai sector (both may not be equal). As per Bengaluru Division Map on South Western Railway website, it covers the distance of 355.900 kilometres (chargeable distance 362 km - maybe due to higher maintenance cost for topography with higher gradients. The difference of real and chargeable distance is due to the difference between Jolarpettai and Mulanur by comparing the distance written in trains schedule of this part and the distance written in Bengaluru Division Map on South Western Railway website). It covers the distance in around 4 hours 55 mins towards Chennai and 5 hours 00 mins towards KSR Bengaluru as 12028 and 12027 Shatabdi Express runs at a speed of (71.78 km/h) in average of both directions.

Speed Its all coaches are of air conditioned LHB coach type which is capable of reaching 160 km/h but it does not touch. Sometimes people become confused because according to Indian Railways Permanent Way Manual (IRPWM) on Indian Railways website or Indian Railway Institute of Civil Engineering website, the BG (Broad Gauge) lines have been classified into six groups ‘A’ to ‘E’ on the basis of the future maximum permissible speeds but it may not be same as present speed.

The maximum permissible speed of the train and the route is 110 km/h. SOUTH WESTERN RAILWAY (SWR) increased the speed limit of KSR Bengaluru - Jolarpettai section to 110 kmph in 2020; Maximum Permissible Speed in Chennai Central – Arakkonam Jn. (DN FAST, UP FAST), Arakkonam – Jolarpettai is 110 kmph as of 2021 but Chennai – Jolarpettai section speed to be increased to 130 kmph from 110 km/h which is yet to be implemented . The train will run at a maximum speed of 130 km/h in Chennai – Jolarpettai section in future after constructing infrastructure.

Loco link earlier was meant to be WAP-4, now It is hauled by a WAP-7 and WAP-5 end to end.
