Question

if you take a amtrak train to baltimore from newark nj does it have to go through a tunnel under the water and also does it have to go over a long bridge? my friend needs to know. pleas give me some info?

Answer 1

Your train will definitely cross over a number of bridges between  Newark and Baltimore but no tunnels.

Answer 2

Alco is correct.  There are no underwater tunnels.  I can think of about three major bridges: one at Trenton, and two in northern Maryland.
