LJN-ASH-BNZ-ML-BBK-GD-GKP this line is in MG owned by NER and LKO-LBH (Dilkusha Cabin)-ML-BBK-AY-BSB this line is in BG owned by NR so there is no junction in Malhaur.
After MG to BG conversion in LJN-ASH-BNZ-ML-BBK this single line owned by NER. But when LKO-LBH (Dilkusha Cabin)-ML gets doubling then ML-BBK double line owned by NR (transfer from NER happened).
So today we can see it like a junction station but from starting time it is not junction station that's why their is no junction suffix in name.
