तमन्ना जहाज के सफर की... क्यों करूं मैं, दिन भर की खुशियाँ लम्हों मे बर्बाद क्यों करूं मैं। - Amir

Got a quick question/doubt.
Can I buy an unreserved super fast ticket
from Bangalore to Tiruvallur
to travel in Lal Bagh express,
get down at arakkonam
and...
more...

then board EMU/local train and get down at Tiruvallur.
Is this valid?
Or
Will I be in trouble that Lal Bagh train does not stop at Tiruvallur and the checking staff questions about it? For sure am not going to travel beyond Arakkonam and going to get down at Arakkonam.
Kindly advice.
