Yes mostly SLP coaches. i think the coaches has been given to swarn jayanti express in his 1st lhb run. No doubt as the train is having RSA with Swarna jayanti express.
As i know that 2 rakes of samta with mixed lhb rake of Prashanti Express was given including pantry car. as it came with ASN WAG9 at 9;30 am at durg on 14 September 2021. Also the rake was standing in aide line of durg junction.
