Why is such a testing going on.. Are they planning PUsh Pull in Pune Mumbai section.. if yes.. i think CR is way ahead of others.. they might deploy push pull there and for 12123/24 and other intercities they could remove the tech halts at KJT (saving of about 10 minutes ) reduce halt at LNL by 2 minutes and increase speed a bit and do the run b/w PUNE & CSMT in 2 hr 45 minutes. Dont know why WR is not applying Push Pull to its Rajdhanis
