Switching of a train from up mainline (line no-3) to platform 1 is not possible by present barrackpore yard layout. And express trains only run through up mainline between Sealdah/kolkata-barrackpore, so it can only arrive on pf3 (14 coach) or pf1A (12 coach)
Only trains from up suburban line (line no-1) can switch to platform no-1.
