To Camden and Beyond!

I have moved the construction concentration up the line and wired and ballasted (gray) about 25' of double track mainline through Camden.

Then I cinder ballasted the 2 holding tracks behind the industrial area and the 3 Camden industrial spurs.



I still need to lay the yard leads (waiting for 2 Peco large radius switches to arrive) and then we can begin to plan the connection to the existing Woodbury, Westville, Brooklawn portion of the railroad. The target is to be running the whole railroad by Christmas.

Now that the initial construction end is in sight, I have started attempting to figure out which of my 758 freight cars will realistically make it onto the layout on a regular basis. (I am selling off the excess cars.) That presents 3 main issues:
          1) Number of cars that will fit on the railroad;
          2) Ratio of railroads represented and
          3) Percentages of car types.


1) To calculate/guess at how many cars will fit I figured I would calculate the yard and sidings capacity and figure on a 50% occupancy to not clog up the railroad (it is nearly impossible to switch a yard to make up a train where all the yard tracks are almost full):

123 cars fit in the Camden Pavonia yard
  10 cars in Camden's 2 additional storage tracks
  15 cars Camden (3) industrial spurs
  29 cars fit in the Woodbury yard (where 3 branches join to drop off cars for consolidation (and icing)
  20 cars Woodbury 5 industrial spurs
  20 cars Westville 5 industrial spurs (will increase when I get around to building the Texaco refinery)
-----
217  /  2 = ~ 108 cars

2) Ratio of railroads represented:
The PRSL was a state forced shotgun marriage between the PRR and the RDG which covered the entire South Jersey area. PRR owned 2/3 so they pretty much ran the show for 2 out of 3 years. The PRSL was somewhat strange because it was  a north-south (and east) railroad with no connections on the southern side. CNJ had an interchange mid-point but the main connection with the outside world was Camden to Philadelphia on the north end (some traffic got routed on the PRR north to Trenton and NYC from Camden). I am primarily modeling early 1950s when south Jersey was loaded with farms and Campbell Soup was a major Camden destination (with most reefers being iced/re-iced in the Woodbury yard).

The PRSL supposedly had no freight cars (but did have some cast off hopper cars to hand-load the steam engines and ex-PRR work cars that they re-stenciled "PRSL").

I am guessing I should use:
30% PRR;
15% Reading
5% to each nearby roads: CNJ, B&O, LV, Erie, NYC, C&O, N&W (2 power plants), and FGE (/PFE: need to steal their reefers).
DuPont and Shell also had plants on-line
That leaves about 15% for misc. railroads.

3) Car TYPE ratios. This is tricky since there were 2 power plants fed by the PRSL. Also every town had 1 or 2 coal dealers (remember those octopus coal furnaces in your basement.) Hoppers dominated the up to 100 car trains running through Woodbury so I probably need at least 50% hopper cars.

Multiple refineries were on line. Texaco is in Westville (and Mobil Oil was on the Penns Grove branch). So I am guessing 20 tankers.

20 reefers (remember Campbell Soup and the south Jersey farms.)

South Jersey also had Owens Corning glass plants requiring sand as did the cement mixing businesses trying to keep up with post WWII road construction. Therefore I need about 10-15 gondolas and covered hoppers.

Box cars were everywhere (and a colorful part of the trains) so I figure about 40. That puts me at 140 which is about 30 over estimated capacity so I guess I will slim down and keep the calculated car type ratios. Once I begin operations that should highlight any needs to change the type ratios.

  1. Looking good Rick. The guys I operate regularly with have a method that is escaping me right now but I'll see them next week and get the reference material and send to you. It does calculations based on online industries (and perhaps offline as well). Generally, that's where you'd start from and go from there with traffic movement.
