Found a Gem of a thing. TAAG 2001/2002 Table No. 12 where all trains were faster than now. Posting it shortly after scanning.
Points to be noted:-
3049(now banned) & 3005(now 13005) was a way lot faster & 3073(now 12331) is faster by 100 mins than current TT. Doon Express was also faster but Archana Express was slower. GS was faster than current TT, so as 4265 & other trains. 13151 then used to arrive JAT at 02.30 am! & 3049(later 13049)
