You will find
lots of miscellaneous maps on this page. Some might even turn out to be useful. Some
Google Earth 3D models will be used as well, mainly because they give those who
have never been to the tunnel a real perspective as to why a train couldn't make
it over the top!

This is the last of many
versions of this map. The purpose of this map is to tell people inside the
tunnel what is directly above them. This map is 99% accurate. If you ever wander
into the tunnel you will notice on the north wall there are numbers every 100
feet. from 1 in the west to 251 in the east. 100 X 251 = 25100 feet, which is the actual length of the
tunnel today including the portal facades. This map's first predecessor is
actually what inspired this website to begin with. The original map was off by
over 1000 feet. This one is however dead on. Just match the number on the wall
you reached with the number on the map and you can see what was directly above you.
The method for making this map
was fairly complicated. First I had to splice together several 1/2 meter per pixel
color satellite images. Then I drew a line from portal to portal. I calculated
the length of the line and the vertical (picture wise) height. Using the mighty
Pythagoras theorem I determined the length of the line I drew. I divided that by
251 and figured out how many pixels equaled 100 feet. then I painstakingly made
a mark every 100 feet and labeled them. Even with the grading inside the tunnel
this is almost perfectly accurate.
This picture depicts to the best of my ability (accuracy not guaranteed, but
hey, its pretty close) the East Portal village. There is some ambiguity to the
grey areas labeled worker housing. Workers also lived further down the road
where there are still houses (not on this map). The point of this map is to give
the reader a general idea of what is where on the east side.

This picture looking east shows in the foreground the site
of the Rowe alignment tower. The crosshair with the red dot in the
background shows the location of the East Portal.
This picture looking north-east-east shows in the
foreground the site of the Whitcomb alignment tower. Next in line with the red
dot is the East Portal, then with the green dot is the Rowe Tower site.
This picture looking west shows in the foreground the site
of the Spruce Hill tower. after that the West portal, then finally the Notch
This picture looking east shows in the foreground
the site of the Notch road tower. After that the West Portal (blue dot), then
finally the Spruce Hill alignment site (purple dot).
This picture looking west shows in order from closest to
furthest: Rowe neck site, East Portal, Whitcomb Hill site, Central Shaft, Spruce
Hill site, West Portal and Notch road site. The crosshairs don't appear in a
perfectly straight line because I have terrain mapping on which slightly throws
things off, especially with a 2000 foot deviation (between West Portal and Spruce Hill for instance).
Mountain Cross Section
This image shows a cross section of the
Hoosac Tunnel around 1870. Notice the offsets on the west end, most likely
indicating digging patterns for water flow (deeper is higher so water wont
Map of Rowe
This is an 1871 Map of Rowe MA. Of
particular interest is the SW corner where the rail line suddenly ends. Notice
the station and hotel. Also notice the road leading up the mountain (present day
tunnel road). The right of way of tunnel road presently is nothing like it is
depicted in this map.
1894 Map of East Camp &
map (courtesy of docs.unh.edu) shows the East
Portal camp as it appeared in 1894. Also notice the buildings further downstream
which include the Hoosac Tunnel station. The new Hoosac Tunnel & Wilmington RR
can be seen following The Deerfield River northward. I do not believe that all
of the houses depicted here were part of the tunnel project, especially the ones
further from the portal. All roads depicted here remain except for the road
following the river south on the Rowe side (former tunnel road)
1898 Map of Central Shaft
map (courtesy of docs.unh.edu) depicts the
Central Shaft village as it appeared in 1898. All roads shown still exist except
for the short dead end which goes off to the SE. Central Shaft road was
straightened out where the dead end branches off.
1898 Map of West Camp & Vicinity
map (courtesy of docs.unh.edu) shows the West
Portal and Shaft camp. Notice the road and buildings on the right hand side.
None remain! Also notice the interesting topography near the buildings which
consists of spoilage taken from the West Shaft. The small road leading from the
West Portal along the stream to the road on the right (present day West Shaft road)
is now for the most part a 4 wheeler trail.
