IR has not been taking the 'Junction' thing seriously. Many stations that have become junctions due to new lines are not get the change in the stations boards immediately.
And IR absolutely hates changing station names! Most of staff continue using the old names only. It is a big pain for them to change the station name when all the staff involved are used to one name for decades, and on top of that the number of changes they have to make in their backend software to add the new station. Its always due to political pressure that they change the names.
