Generally college campus with a small acre do not have bus facility. Many like bit Mesra also don't have them inspite of being in 800 acres to run within the campus. They go outside on purpose.
So generally campuses have buses but for college personal use

Hi

Good morning.
Please mention college.
Government colleges doesn't have bus facility.
Most of the private colleges have bus facility.
All the best.

Hi dear,

       Kindly specify the question that which college do you want to ask about. These days all colleges have bus facilities which a student can avail. Just you have to go to the transport department of the college where you got admission.
