The Commuter Rail Hub is efficient, clean and well appointed with stores for coffee, snacks and a convenience store.
The T station is a walk, but the tunnel keeps commuters warm.
The station also has indoor access to an excellent food court, called the Hub, not to mention access to a Start Market grocery store downstairs. So, whether it is access to the T (Orange and Green D & E lines, the Commuter Rail hub, or the Amtrak to Maine, this is a very convenient commuter station.
There are buses running from outside the hub on Causeway street to Cambridge - these are quite convenient except on heavy snow days (when the T is the better option for commuting into Cambridge (Green line to Park to Red line for Cambridge).
