When identifying wheel numbers on cars, from which end should you start?

When identifying wheel numbers on cars, you should start from the "B" end. This is an established practice in railroading, ensuring consistency and accuracy in tracking and managing railroad operations. The "B" end is typically designated as the conductor's side or the side where the operations such as uncoupling and inspections are more commonly performed.

Starting from the "B" end allows for a standardized approach that helps in communication among crew members, as everyone knows to begin identifying numbers from this end. This practice minimizes confusion and enhances safety, as the identification process is uniformly applied across different trains and cars.

In contrast, starting from the "A" end, "C" end, or the middle of the car could lead to inconsistencies and potential errors in operating procedures, as these points do not have a widely recognized standard in the same way the "B" end does.
