I am traveling home from NWK on the 43 Pennsylvanian. Are the business class car(s) marked on the outside or how do I know where to go? I am also traveling, next Sunday, on the 44 Pennsylvanian from HAR to NWK in business class. So I assume the same thing applies boarding in HAR as NWK (as far as finding the business class car). By the way (for anybody who looked at my last few threads) I made it to EWR on the train from HAR and I LOVED it. No more flying for me! (at least to this customer's office).
