Donald..one of those questions where 10 eng'rs give 10 diferent answers...but here's how a lot of us rate them: GE44CW (DC)..powerful, but tend to slip heavily. I work on our trackage rights over the Moffat (D&RG/UP)line and when they slip in the curves (reduce their loading or capacity) you can get in trouble quickly. SD70MAC-very good, SD75-very good, SD-40-2:to us dinousaurs still the best. One problem is lack of extended range, the ability to maintain amperage at 10 mph and lower.Some of the ex-BNs are retrofitted with this feature, as all Santa Fe's are. The EFFECTIVE RANGE of DBs is 18+ mph, as the wheels are turning fast enough to generate amperage/power. Typically,the heavier engines and 6 axle trucks provide the best db adhesion and effect. All BN and Santa FE Geeps 38's, 39's, etc. are equipped with DBs, but aren't too effective due to their weight and power, better than nothing..BTW..with the cost of fuel skyrocketing the use of DBs instead of air brakes when possible, is now the rule. Hope this helps.....Terry
