BIO-TOILETS IN OUR INDIAN RAILWAY COACHES ARE GOOD FOR TRACK MAINTENANCE .BUT DESIGN HAVE TO BE MODIFIED SO AS THE INAUSPICIOUS FECAL MATTERS SHOULD NOT BE SEEN ( INVISIBLE ) BY THE NAKED EYES. BIO-TOILETS ARE THE WORST THAN ORDINARY MUNICIPAL BUS STAND INDIAN STYLE TOILETS.
    I hereby offered my suggestions to modify Bio-Toilet Design in our Indian  Railway coaches.

systems are good and welcome one .The track maintenance Gangman  and other  staffs are totally freed from the inauspicious fecal matters( excreta ) in the track.
   Central Government also banned manual scavenging and like that all our track maintenance staffs also freed from these inauspicious and unhigenic matters.
  But its design have to be modified so as the inauspicious and ugly fecal matters should not be seen in the Bio- Toilet by the naked eyes in the early morning time.
   At present the inauspicious   fecal matters are floated in the Bio Toilet vertical stem portion and seen by the naked eyes in the Toilet .
  I enclosed photos taken in the  Train Bio Toilet fitted coach.
     So I suggested that the Vertical Stem portion in the Bio-Toilet systems shall  be modified as S shaped Stem portion so as the inauspicious floating matters should not be viewed.
  I also attached a photo of S shaped Stem .If this modified  S shaped Stem in the Bio-Toilet,then all the passengers are freed from viewing the inauspicious matters.
  Moreover i informed that I terribly  feel dry vomiting sensation in my empty stomach in the early morning after seeing the matters during flushing . With great difficulties I take one photo.I could not be  taken ( unable due to vomiting ) video of the inauspicious floating matters .
  So I determined that here after should not utilized the present Bio-Toilet systems.
  So I prayed and begged  our IR authorities to suitably modified the Bio-Toilet systems so as the inauspicious matters should not be viewed from the top in the vertical stem portion . 
  Moreover most of our staffs and sensitive passengers are experienced in viewing the inauspicious matters .
   On behalf of all the sensitive and all the religious  orthodox  passengers I once again requested our IR authorities to modify the present Bio-Toilet systems .Vertical stem portion may be suitably modified as S shaped or Zig-Zac shaped or any other form so as the inauspicious matters should not be viewed by the passengers.
   I feel extremely sorry to write this ugly  matters but my inner mind  sentiments insists to write since lots of people hesitate to write/inform.
