Poked wih needle in butt in train seat don't know needle type. so is there risk 4 hiv do i need testing?

Very iunlikely: However , you have risk of infection with common bacteria . If your immunization with tetanus is not up-to-date , you may need one . Make sure if you see any swelling , pain , tenderness and or fever see your doc . Chances of HIV is very very unlikely . Good luck.

You're still asking?: You've written other questions in which you've indicated somebody stuck you while you were on a bus, and other stuff over the past few days. You should already have asked your personal physician about antiretroviral prophylaxis. Please do this.
