GN W-1 B-D-D-B electrics.
Imported by Custom Brass models in 1976.
These were equivalent to the Big Boy only the lead and trailing trucks were powered.
These were the largest single engines electrics ever made.
They were 15.5' high and I read where the crew, initially, ducked when they entered their first tunnel.
The GNRY had 2 of these; 5018 and 5019.
The 5018 has a non sound decoder.
I installed a Tsunami electric decoder in the 5019.

I acquired the 5018 pre-painted by the previous owner.
