Yo dude, need some help.
I was tryna book some swanky 1AC seats on the Deccan train for the 18th Jan from CST to Neral. I wanna catch the toy train from Neral.

Went through all the hassle of booking and kept gettin' this message
SRC DESTINATION PAIR OF SAME SUBURBAN AREA IS INVALID

What's this supposed to mean yo?

Thanks

Kripaya madad karo.
Deccan train se 18 Jan ko CST se Neral ke liye 1AC seats book karne ki koshish ki. Mujhe Neral se toy train leni hai.

Booking ke saare steps follow kiye par hamesha yeh message milta hai
SRC DESTINATION PAIR OF SAME SUBURBAN AREA IS INVALID

Iska kya matlab hai kripya batao?
