My wife has a doctors appoint in a couple of weeks in NYC.After we finish her app we plan on taking the #176 NERegional on up to Boston. It departs at 3:30 pm giving us approx. 30 minutes to get from E 36th and Park and onto the train. I have never caught a train at Penn Station before and will not have a lot of time to get lost. I would like to jump out of a taxi and into a Redcaps cart to get us on the train. Is it possible to get a Redcap at street level? What if we miss that train, can we use our tix on the next NER going out? Any ideas,suggestions or just reliable information will greatly appreciatted.
