Grand Central because you can get Metro-North trains, which run on a schedule and are cheaper than Amtrak. At Penn Station, you can get Amtrak, which runs less frequently, and is more expensive. Amtrak stops only at Penn Station and Metro-North only stops at Grand Central
Both groups of items weigh nothing at all. * Grand Central in New York City is not a station but a "terminal." Trains do not run "through" it; * The "paper" used to make US paper money is not made from wood pulp but is composed of 75% cotton and 25% linen.
Yes, Amtrak trains run from Penn Station to Yonkers. Metro-North trains also run from Grand Central to Yonkers.See the Related Link below for Amtrak's home page. The station code for Penn Station is "NYP" and the station code for Yonkers is "YNY."
Layover
The only subway lines that go through Grand Central Station (42nd and Lexington) are the 4-5-6 (the dark green line) and the 7 train (the purple line). Also, the S shuttle train (color code grey) runs between Times Square and Grand Central Station. See the Related Link below for a New York City subway map.
There is no subway line under Madison Avenue, although there are bus-only traffic lanes. Two blocks east, the 4-5-6 trains run under Lexington Avenue (and Park Avenue below Grand Central).
The best place to find out what times trains run is to look on the train company websites or go to the train station. If people go to the train station to find out what time the trains run, they need to go early, so they have plenty of time to plan.

Cal Trans run trains to a station close to AT&T Park. The station is one block from the stadium. Muni run buses to a stop at the same transit station.
The 1, 2, and 3 trains go from Times Square to Penn Station. The A, C, and E trains run parallel, going from Port Authority to Penn Station. However, the Port Authority Station and the Times Square Station are connected underground.
Subway trains, like other trains, run on rails.
