It is set at an angle to North Main Street, from which it is separated by the grassy area of Veterans Square, and faces roughly southeast.

It is built out of granite and red sandstone, and has a central area, the former waiting room, that is 2-1/2 stories in height, with a pyramidal roof.

That area is flanked by single-story sections with tall hip roofs, and its front is dominated by a porte-cochère with large rounded arches.

The waiting room area features a large sandstone fireplace, and has a floor covered in patterned tile.

The size and scale of the station were due in part to the activism of Charles Busiel, a local businessman who was later governor of New Hampshire.
