What old coaches sir ?
First EOG is 2022 made second EOG is 2023 made, all three GS coaches are 2024 made, seven SL coaches are 2024 made and last SL is 2019 made.
One AC 3 tier and all three economy AC coaches are 2022 made. One AC 3 tier in Humsafar livery is 2019 made and one AC 3 tier is 2013 made whereas the AC 2 tier is 2014 made.
I...
more... still consider 2022 made coaches as new ones. So out of 20 coaches 16 coaches are new 2022/23/24 made, 2 coaches are 2019 made which also are not so old to speak. Only one AC 3 tier and AC 2 tier are old in that sense.
