Historic Preservation of the Dinky in both
Function and Form
Purpose of Historical Preservation
• Preserve the Function and Form of Historically Important elements of the Built Environment.
• Dinky: – Functioning since 1865– Current Form since about 1915– Station moved in about 1986 to current location

This would be the 3rd time the station has moved towards The junction.

It then 2st moved 170 feet to create better E-W mobility for Forbes Student
from: the end of the platform, to: the Freight Building
The Conflict Arises from the current 3rd attempt at a Dinky Land Grab Land Grab
Walk&Ride Accessibility Lost by Moving the Dinky Terminus South
Assumptions:1. All walk in a straight line to the station2. All Walk&Ride trips production/attraction are
uniformly distributed in the half plane north of the current terminus.
3. Walk&Ride Area Lost =~ R*D*(2*cos q + sin q ) where R = prime walk distance
D = Distance Terminus moved (460 ft)q = sin-1 (D/R)
¼ Walk&Ride Service Areas49% Prime Walk&Ride Area Lost http://www.daftlogic.com/projects-google-maps-distance-calculator.htm
Nothing is gained to the south to off-set the losses to the north

1/2 Mile Walk&Ride Accessibility Analysishttp://www.daftlogic.com/projects-google-maps-distance-calculator.htm
Conclusions: Walk&Ride Accessibility Analysis
• 49% loss of ¼ mile prime walking area implies loss of Walk&Riders could be as high as 49% and a 25% loss of Dinky ridership.
•24% loss of ½ mile walking area implies at least a 24% loss of Walk&Riders and at least a 13% loss of Dinky ridership
