Dedicated to Sharing the Heritage of Redwood Empire Railroading
Working on decoding old NWP concrete mileposts at our museum in Tiburon. We have one indicating 79 miles (town of Fraser south of Cazadero) with a letter 'B' below the mileage. We have another indicating 13 (I think is Baltimore Park in Larkspur) with the letter 'I' below the mileage. Understand the mileage, but would like more information on what the letters mean. We have three other concrete mileposts at the museum and would like to be able to explain their coding to visitors.
