U can see SRC-HAPA SPL, SHM-JP SPL , SRC-MAS SPL start running again in few days which was earlier till feb 2019 end....
SOMANKO u cannot count these rakes as spares because SER using these 2 rakes in running these specials thoughout the year...u cannot break the rake composition and used these coaches in other trains as an when required except in case of huge emergency.... Spares are those coaches which are kept idle so that it can be used as an when required in any trains in case of breakdown of any coach in use...
