Yes. I’ve verified with NJ Transit, that NJ Transit will have rail Transportation from Secaucus-Hub to Metlife Stadium on the day of the Siyum Hashas.
Please remember to buy the train tickets BEFORE you board the train, at the vending machines located in Penn Station NY and Secaucus Junction station. The price is about $2.75 one way. Buying a ticket on the train has a $5.00 surcharge.
The Train to the Siyum will leave from the “Lower Level” G & H tracks.
