The order of the coaches has reversed (compared to the schematic shown on indianrailinfo. I travelled 12262 / 12261 this month and found that when leabving from Mumbai CST the Bxx coaches (AC 3-tier) are nearest the loco and Axx / Hxx are towards the end of the rake. Also, A4 is officially called AE1 for the time being. Please update the scheme. Thanks.
