My scheduled arrival at FRA is at 6:55 AM on Sep 17. And the train travel from Frankfurt airport to Magdeburg takes between 3:45 and 4:20 hours. And then to the booked apartment in 12 mins by taxi. I need to be at the apartment by 3 PM, without delay (landlord has other appointments and so, needs to head back after my check-in).
After finishing the arrival process (non-EU security check, collect baggage, customs check if needed) at the airport, I need to transfer to Term. 1 for exit and reach the platform at Fernbf (long-distance one). Based on all the trains I have checked and considering flight and arrival process delays, the only likely route is this one - to hop on ICE 992 (10:09) for a 6 min. transfer to IC 2441 (at Braunschweig Hbf), to reach Magdeburg at 13:54. Of course, if the ongoing train (ICE 992) gets delayed, then I won't be able to catch the connecting train.
There is another option, go to Frankfurt (Main) Hbf (taxi or S-Bahn) and hop onto any of the 3-4 trains starting from 09:02 to 10:14.
Of course, if I am able to catch any train before (any Fernbf or Main Hbf), it would be a bonus, and anything later will definitely not work.
The last resort which I am trying to avoid is, to book a hotel room for a night and then, check-in to my apartment next day.
Any help would be of great help.
Thank you.
