Hello all
You may enjoy seeing the Daylight by John Harmon & John Kresse in standard gauge made in the early 80's.
5 engines were made ..center two drivers are blind ...or you would need 20' to turn a circle ...shown running on 87" diameter track.
Please see link for Daylight in motion .
I do not think it was ever run for any serious time ..,so engine is still stiff ..,needs a few miles to work it in.
Down the road I'll post again when engine is pull a few cars
Cheers Carey
