About This File
The Norfolk and Western Railway (NW) used the HL Class 40 ft, 2 bay "fishbelly" hopper cars to transport coal during the early to mid 20th century. These Late Steam/Transition era cars have the "sloped side sheets" with original road numbers 22000-25999, 38000-39999, and 68500-69499. 
Some HL class were rebuilt into H9 class around 1949, this marked the beginning of the phasing out of the design. By 1960 they were using different cars and different paint schemes, and the Norfolk and Western was running diesel on its mainlines starting in 1959. 
Simply unzip the "CT14 - Norfolk and Western HL Class Hopper Cars.zip" file into your plugins folder.
Remove the "Norfolk and Western HL Class Hopper Cars" folder from your plugins folder (normally in Plugins/CT14/Norfolk and Western HL Class Hopper Cars". Lots which use these props will be a little bit emptier.
For SimCity, these cars have been rendered as HD props in a variety of angles and filled with coal in three variations, along with empty car versions.
Orthogonal (3 load variations plus empty):
- 90 deg
Diagonal (3 load variations plus empty):
- 45 deg
Curve Fitting Angles (consecutive angles' loads will generally vary, plus empty versions of all):
Left and Right versions of:
- 5.625 deg
- 11.25 deg
- 16.875 deg
- 22.5 deg
- 28.125 deg
- 33.75 deg
- 39.375 deg
Fractional Angles (3 load variations plus empty for each pair of angles):
