Apart from the vestibule area even the sounds within Western/Indian Toilets of ICF Coaches are quite similar (But less than that of the vestibule area). LHB Coach Toilets are quieter due to their commodes being closed just like home toilets. As a kid I used to think that the commode (Both Indian/Western) makes the sounds from it's hole but actually they are the parts and bolts beneath the toilet that emit such sounds. Once a Bollywood Music Director had said (Probably Mr. Anu Malik) that an Indian Train Toilet is the best place for Music Directors to compose new tunes for the sounds they emit... Gee ;-D
