Freight reference

Domain reference for the freight this plant receives — wagon families, the load-type code key, known codes, railway zones, and the wagon-number scheme. This is the foundation future features build on.

Load-type code key

A code like BOXNHL reads left to right:

B Bogie wagon — 4-axle system (not the legacy 2-axle design)
O Open top (gondola profile)
X High-sided walls
N Pneumatic / air-brake system
C Covered (weather-protected body)
HL Higher Load — lighter materials (e.g. ferritic stainless steel) cut deadweight
S Specialized / high-capacity 25T axle-load variant

11-digit wagon number

Painted on every wagon; not in the FOIS feed, but decoded here for numbers captured elsewhere.

DigitsFieldNote
1-2 Type of wagon e.g. 10-14 denote open-wagon series like BOXN variants
3-4 Owning railway zone e.g. 01 Central Railway, 02 Eastern Railway
5-6 Year of manufacture two-digit year
7-10 Serial number unique wagon serial identification
11 Check digit system integrity check

Owning railway zones (digits 3–4)
