Denny D’s Did You Know - High and Wides

The other day I overheard a conductor telling the dispatcher about a dimensional load in her train. Great job. While excessive dimensional loads are pointed out on the title page of your train list, dimensional loads are only shown to be in the list of cars. There are similar requirements for both, so I thought that this would be a good opportunity for a refresher.

 

Item 5-A in the SSI covers the requirements for High & Wides as well as high value loads. There are a few similarities as well a one major difference between dimensional and excessive dimensional loads.

 

Similarities 

 

• Must be as close as possible to the head end, but no closer than the 6th car from an occupied engine when train lengthsl permits. Notice the word, occupied. HAZMAT rules apply to locomotives whether occupied or not. A little different here.

 

•GCOR 15.2 specifically says that when you are to operate through a Form B you must notify the foreman of Excessive Dimensional loads. Although not required, I recommend notifying them of dimensional loads as well. This is important because there is often not a lot of room as you pass on-track equipment. Simply let them know of their presence in your train and the measurements shown on your train list.

 

•You must have a job briefing with the dispatcher regarding both excessive and dimensional loads. This would also apply to foreign railroad dispatchers as well.

 

•Subdivision specific speed restrictions, such as the 30 MPH locations on the Chester Sub, apply to both. Not just excessive dimensional loads. This is why it is always critical to review your paperwork for dimensional loads. The dispatcher can allow you to go through those locations at maximum authorized speed if he determines that there are no trains in the area.

 

Differences

 

•Excessive Dimensional loads require a Form C Bulletin for each subdivision you will operate on.

 

•Dimensional Loads do not require a Form C. Remember, you must still job brief with the dispatcher if you have them in your train.

 

Whether you have Dimensional or Excessive Dimensional loads in your train, it is critical to know that they are in your train and understand the rules regarding their handling. All the instructions in Item 5-A are important to understand and follow.
