well then read once again what i am pointing out and then comment...if the coach is in bad condition...if its 17 made or 10 made or 1990 made..its has to be replaced and they surely know what they are doing and especially SCR when it comes to maintenance ...if they are maintaining this properly, i guess these coaches would have been in much bad shape than now...
.
whether its ICF/LHB/ICF/Hybrid LHB ..if the coach is ought to be replaced due to problems..it gets replaced and if they think it can continue for...
more... few more months till next POH schedule considering the situation of the coach...they will run the same by taking care of maintenance...
.
if you think maintenance is what lacking in SCR then i don't have anything else to comment here too ...
