Diesel Era Coming Soon

Rock Island GP40s

Rock Island 347 is an uncommon member of the road’s GP40 roster as it was among the few to receive red-and-yellow with large speed lettering. This look was the as-delivered dress the road’s last GP40 order, which was the 4700-class. Watch for Rock Island’s fleet and more GP40 coverage in 2023 in Diesel Era. — Kevin EuDaly collection
