The trains operating on this slot dont have stoppage @Kalyan and they dont belong to CR as well so not many chances of additional halt, And very rarely suburbs get additional stoppages later unless there's some interference from high command/politicians like the case of LTT-NZM
Another train GKP-LTT-GKP SF skips Kalyan but regularly the passengers resort to chain pulling for 12541 to get down @Kalyan and in order to take some strict action RPF's had to be deployed on the PF at the time of crossing of the train and nab the passengers who get down here :P
Authorities...
more... say NER is not willing to comply in this case...
