The RER was actually a tariff subject to the same publication rules and regulation as other tariffs. Nearly all freight rate tariffs made reference to the RER.

There were published rates that related to the capacity of the car or specified a car type or dimension. For example, when a rate specified “loaded to full visible capacity”, the defined capacity for a car came from the RER.

It was simple in the steam era. Multi-level per diem, hourly car hire, regulatory interference, etc. all came after the mid 60’s. There was a single per diem rate for all railroads, set by the AAR. That goes back into ancient history. It was diffcult to make a change in the rate because it required a vote of the railroads, weighted by size. Big eastern roads had the most weight and tended to resist increases.

The numbers came from the mechanical department, which needed to have the numbers to that level of accuracy to have they car built. The answer to your question in many cases may simply be if you have the exact number why bother to round it.
