Had seen this train last week at Ernakulam North station. Train was on its way to Guwahati. Quite surprised that many of the bogies did not have the coach number mentioned (Eg S-1, S-2 etc) hence was a bit difficulty for passengers trying to find out from passengers inside and confirming which coach it was. The same issue is seen in Ghy Ernakulam express. The least the railways can do is to provide some kind of assistance to passengers regarding this aspect
