The Mount Washington Turnpike was chartered in 1866. Construction commenced the same year under the supervision of long-time BC&M bridge-builder and railroad superintendent, John Jarvis Sanborn. The turnpike spanned the six miles from the former Tenth New Hampshire Turnpike (the road from

As construction of the BC&M branchline approached the Cog base area in the spring of 1876, the Cog Railway directors voted to extend their track down to meet it at the area where the grade became so steep the friction-driven branchline engine could climb no higher. The two lines met at the "transfer station". This photo shows the earliest configuration of the transfer station. This basic configuration was used from 1876 to 1895, with additonal buildings added, as needed. From the first trip, the branchline train from Fabyan travelled in reverse,(coach first) due to the steep grade—just as the Cog “backs up”as it ascends the mountain (the downhill locomotive offers the greatest protection against possible incidences). The first Marshfield House is visible in the upper left of the image. Kilburn stereo view.

This image tells many stories. Starting at the left, coal may be seen between the open wooden building and the tracks. The Cog Railway locomotives transitioned from burning wood to coal between the seasons of 1909 and 1912. The most noticeable aspect of the image is the two rails that stretch into the distance. The 1895 realignment of the transfer station enabled a switch from the branchline onto the Cog to bring coal to the shops at the base. Although the Cog locomotives are nominally standard gauge (4 feet 8.5 inches), they are actually 4 feet 8 inches, a half an inch less than standard. This small difference required the additional rails that can be seen in this photo.
