Turnpikes and Roads in B & O WINTER - The Good, the Bad and the Ugly

Moving units and supplies to where they need to be at the right time is a critical aspect of campaign simulation. Railroads are a major asset in accomplishing this, which is why destroying the enemy's railroad network always has a high priority. Roads are also important, but they are often subject to weather conditions.

Roads in the simulation are given one of four classes:
  • Primary
  • Secondary
  • Tertiary
  • Other
The "Other" class is highly unpredictable, but usually very poor.

The roads used in the simulation can be viewed on the campaign map for the simulation and are as follows:
Road Class
Road Name
Terminus
Towns on Road
Primary
Valley Turnpike
“The Pike”
Williamsport (MD) – Mt. Jackson
Williamsport (Md), Hainville, Martinsburg, Darksville, Bunker Hill, Winchester, Kernstown, Newtown, Middletown, Strasburg, Woodstock, Edinburg, Mt. Jackson
Primary
National Road
Cumberland – Dam No. 5 Turnoff
Cumberland, Hancock
Primary
Northwest Turnpike
Winchester - Greenland
Winchester, Petticoat Gap, Cacapon Bridge (Bridge), Pleasant Dale, Frenchburg, Romney, Burlington, Williamsport (VA), Greenland
Secondary
Romney-Petersburg Rd.
Romney (junction with NW Turnpike) - Petersburg
Romney, Mooresfield, Petersburg (via Bald Hill and Trough Mountain)
Secondary
Cacapon and North Branch Turnpike
National Road Junction – Cacapon Bridge
Springfield, Clasor’s Ford (ford on South Branch), Slainesville, Clayont Cacapon Bridge (via road north of Grape Ridge, Candy Ridge and Parker Mt.)
Secondary
Martinsburg Turnpike
Frenchburg - Martinsburg
Frenchburg, Slanesville, Sherrard, Bloomery Gap (gap), Gano Town, Shanghai, Boyd’s Gap, Martinsburg
Secondary
Old Town-Romney Road
Old Town - Romney
Old Town, Springfield, Hanging Rock, Romney
Tertiary
Old Town Road
Martinsburg Turnpike Junction – Potomac Turnpike Junction
None – passes through Spring Gap Mountain and fords Cacapon River
Tertiary
Potomac Turnpike
Cumberland – Cacapon and North Branch Turnpike Junction
Cumberland – Old Town (fords Potomac and crosses B & O)
Tertiary
Hampshire and Morgan Turnpike
Paw Paw Tunnel – Martinsburg Turnpike Junction
None – only road access to Paw Paw Tunnel
Tertiary
Parker Road
Springfield Junction – Cacapon North Branch Turnpike Junction
None - Fords South Fork
Tertiary
Old Romney Road
Clayton – Suspension Brigade
Clayton, Three Churches, Suspension Bridge (bridge)
Tertiary
Pugh’s Road
Junction near Clayton – Pleasant Dale
None
Other
All other roads



Primary Roads (such as the macadamized Valley Turnpike) greatly enhance the speed of march and thus the distance covered during the day. Base marching speeds are affected by the road class they are on as follows:
Road Modifier: Roads are divided into four classes, with a marching speed modifier for each class. Marching speed changes at the time a unit enters a different class of road.
Road Class
Modifier
Primary Road
+ 1.0 miles per hour
Secondary Road
+0.4 miles per hour
Tertiary Road
+0 miles per hour
Other Road
(unreliable, usually poor conditions)
Random modifier from – 0.5 miles per hour to -1.0

Precipitation affects marching speeds and the modifier is applied differently across road classes:

Precipitation Modifier: Rain or snow really messes up the road and slows down the march. The precipitation modifier is applied daily based on road class. “Other” roads are unpredictable. A four-sided die is rolled to determine the modifier for each “Other” class road in the event of precipitation.
Road Class
Modifier
Primary
-0.04 miles per hour  per 0.1 inch of precipitation
Secondary
-0.1 miles per hour per 0.1 inch of precipitation
Tertiary
-0.14 miles per hour per 0.1 inch of precipitation
Other (Roll 1)
-0.2 miles per hour per 0.1 inch of precipitation
Other (Roll 2)
0.24  miles per hour per 0.1 inch of precipitation
Other (Roll 3)
0.3 miles per hour per 0.1 inch of precipitation
Other (Roll 4)
0.4 miles per hour per 0.1 inch of precipitation

Control of roads will make a difference during the simulation.
