Mike,

I am attaching the engineering study for Huger Tunnel.
It is a large file and I hope the moderator will allow it to go
through. In this you will find what options were considered and why
they chose the one that they did. A lot of thought went into this as you
will see. If you want to re-visit the good old days, hopefully we will
have something for you to read about Christmas.

*Subject:* Tunnel design question

Does anyone know what factors went into the separated design of Huger or
Montgomery tunnels versus both tracks through the same bore like
Elkhorn, Davy and Roderfield?

Are there other separated tunnels (other than Hatfields, which were
bored at separate times?)
