Yes SK has the 3rd LHB rake.. I travelled by it last Thursday from NDLS to Pnbe.. the spare rake though does not have a full H1coach ...Instead it has a composite HA1... I was lucky enough not to be downgraded but several were shifted to 2Ac in the HA1 coach... the attender confirmed this was the spare rake and it runs with HA1 ... rest coach composition is same.. however the 1ac didn't have the same feel as ghe regular rakes and I found it to be less comfortable than the usual ones. I will be travelling back tomm and hope to get the regular rake. .
