I strongly recommend clicking on the TRAINS link to BNSF and joining the Friends of the BNSF. YOu will find lots to interest you. I just spent a half hour listening to Ross discuss infrastructure needs, and found my limited time on the internet well spent.
Dave, is pretty much Spot-On!
It is an interesting web site and contains an number of interesting videos.
One that I have enjoyed is a pre-BNSF Traffic apparently traversing Abo Canyon. Featuring some of the Santa Fe Warbonnets and BlueBonnets snaking their way into the Canyon.
Certainly seems to be worthy of registering and frequenting! [tup]
