No. We have 4 TATA Steel Liveried and currently no loco is fixed.
Always LSA is there between 12814 and 18615.
LSA is followed sometimes between 18616 and 12813 but not always like 12814 and 18615.
Yesterday 18616 Kriya Yoga came with 37029 and went with 12813 Steel. So yesterday the LSA was maintained.
