Moodna Viaduct

That's a good point, Pumpers. I have noticed the CR track charts are not quite as detailed as the old Erie/E-L charts, in that the many ups and downs of actual gradient changes are smoothed out into an average grade. And I have not been able to find a track chart from the former E-L NY Division.

The person who would know for sure is Chief Troll; I believe that he was division engineer for the NY Division back in the E-L era.

EDIT: I went back and looked at the 1991 track chart to see what the grades are in the vicinity of the Portage Viaduct, and they DO appear to be very detailed.

Nice video. Reminds me of what the Kinzua Bridge at MT Jewett looked like before the fall.

Don't know how I stumbled on this about 15 years after my post just above. In response to the previous post, from Google, I found that BS Tower was apparently on the east end of the viaduct:

I dusted it off for you LOL.

The post I was responding to was actually at the end of the first page of posts:

Thank you everyone for the helpful information you gave me.

Since we are still on the subject of Moonda, does anyone know where was the actual location of the control tower (BS call letter?) on the east end of Moodna Viaduct where the Graham Line went down to single track to cross the bridge?

Thank you for your help.

Sincerely,
Walter Conklin
