I'm trying to figure out your subway :-) I'm sure it's not that difficult!
I am staying at the Sheraton and need to get to North Station for the train to Salem. Now from looking at the map I could walk to the Prudential (Inbound) Station and get the Green line E train direction Lechmere or would I be better walking to Hynes station for more of a choice of trains B, C or D?
I've only half got my head around the difference between an Inbound/Outbound train, where is the Prudential station - Outbound? I'm sure I'm missing something here.
