TCW Puducah rebuild pulls up the grade past the once ubiquitous Grizwold 'STOP' sign crossing signals in summer 1993. (Douglas Dr. Golden Valley, MN)

When this line was still the MN&S these signals were scrupulously maintained and gleaming silver. Under the SOO they were neglected and rusty.

These type signals are very rare to see today and what ones are still around often have their 'STOP' signs removed and merely use the lights and bell.

Today the Grizwold Signal Company operates under the name SafeTran and is still a Minnesota company. http://www.safetran.com/signal_equipment.asp

Originally shot on Kodak Gold 400ASA with a non-descript Kodak 'point and shoot'. Then re-shot RAW at 100ASA. Colour curves were used in Photoshop to correct negative orange cast and then inverted. Then brought into Aperture for further tweaks.
