"A trolly layout on the go"

[Trolleyfan]

The East Penn groups layouts in HO and O scales predate the Northwest Traction Group by a few years. The East Penn Standards are for double track modules while the Northwest Traction Group uses single track. I've built modules to the East Penn Standards since the early 1970's, I'm getting ready to build a few to the Northwest Traction Groups single track standards because they reflect the norm for most Midwest traction properties. I'll probably build a transition module so I can combine the 'old' with the 'new' and be able to use my existing modules together with the new ones.
