The helix between Lewistown Junction and downtown Lewistown has been completed and made operational.

Heading east on the Lewistown Secondary, the line enters the helix just east of the scale house behind the Lewistown station -- at the bottom center on the above photo. The helix exits at upper left where it will come across the Juniata River into downtown Lewistown.

The helix was a kit from Ashlin Designs. Designed for two tracks, I needed only one, so the end result is an approximate 27" radius with a 2% grade. The kit went together easily and is sturdy and firm. This proved a very cost and time effective solution. 

The helix is located directly below Mann's Narrows, which is why I had to finish the scenery in The Narrows before tackling this section.
