Metro North and (especially) LIRR have another problem with the double decker cars at Grand Central.

National Fire Protection Association (NFPA) standards for fire safety are a limiting factor in the operation of GCT — especially for the lowest platforms. A full passenger load that is discharged from a train of double decker cars may not be able to evacuate within the two key time limits established by the NFPA code for train stations: 4 minutes to clear the platform and 6 minutes to get every passenger from a train out of the station entirely.

Thanks for the good info, especially as you have an engineering background and some experiece with GCT.

Only time I rode a double-decker commuter train was on the Metra in Chicago. I did like the experience of being higher up. You got a better view of things.
