Question Detail:

Q1.   Does a woman travel alone more than 52 miles (the distance at which NAMAZ is KASAR)? In other words does a woman travel with other passengers like in bus or train but without any MEHRAM?

Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
Although it is prohibited for her to travel alone without a mehram, if she does travel alone she should make qasar of her namaazes.
And Allah knows best
