These grey GP-9 has orange stripes and a large white circle 'G' logos. They were built in December of 1957 by the Electro-Motive Division of General Motors as part of build #7546 for Boston & Maine, which was purchased by Guilford Transportation Industries in 1983. Many of these locos were repainted during the 1990s to the Guilford Rail System paint scheme, still using the Springfield Terminal reporting marks.
