Thats bcoz of PF length constraints at CSMT.Some can handle 22 coaches, Whereas some 16.

---

Out of 16, Only 13 for passengers. Atleast, they need to consider attaching 3 SL and 3 3AC or replace some 3Es with 3ACs.

PF length restriction at CSTM. Work is going on, soon it will be 22 coacher.

This train has already had a very bad CC since LHBFication, out of 7 3E, hardly 3-4 fill up fully regularly, another issue is, the train Physically has 3 GS, but One GS is marked as RMS so that GS is unavailable for Public. CR messed this train really badly, Ideal CC would be: LOCO EOG HA1 A1 A2 B1 B2 B3 S1 S2 S3 S4 S5 GS GS RMS SLR

A few PFs @ CSMT has underwent increase in length of PF lately.
Hence, any advantage for 22159 ?
