Manned helpers in the US and Canada.

Fortunately I retired before PSR hit my carrier. My comment was occasioned by the number of TSN reports I have read about the many derailments occasioned by multiple forms of brake failure - both employee practices and maintenance procedures.

Even before PSR employees looked for the ‘short cut’; in many cases not realizing the disasterous position that short cut was placing themselves in.

The BNSF uses manned helpers on th Pikes Peak subdivision between Denver and Pueblo on long and heavy trains to get overth divide. Denver is at 5000 ft, the top of the divide is at 7980 feet, 50 miles south of Denver, Then down to Pueblo at 4600 feet. in 60.1 miles.
