Overall TT is awesome and I must say that, the train will definitely superhit in SDAH-NJP route. I think, coach composition will be like this: GEN: 2+2, SL: 6+2, 3A: 2+1, 2A: 2, HA: 1, SLR/SLRD: 2, HCPV: 1.
From SDAH: LOCO-(HCPV-SLR-GEN-GEN-S1-S2-B1)-S3-S4-S5-S6-S7-S8 -B2-B3-A1-A2-HA1-GEN-GEN-SLRD= 21 coaches. () are the slip coaches.
