If you mean trains are underutilized, yes.
If you are suggestiong there need to be more passenger trains, no.
Passenger trains are a relic of the 19th Century and have no practical use except as tourist attractions and museum pieces.
But the governent is always a little slow to learn.
I meant, that passenger trains, or just boxcars might be an option to help evacuate a city. Load the people who don't have cars or are willing to leave the cars behind and ship them out on trains.
I'm not suggesting that we need more passenger trains. Just that maybe FEMA should be able to get some boxcars or passenger cars to a city quickly and use them to evacuate.
