New Study Finds That DMU Operating Cost Savings Add Up. It’s Like Purchasing Your Rolling Stock at As Much As a 69% Discount.

A new paper, “Economics of FRA-Compliant Diesel Multiple Units (DMUs),” details the significant cost savings that Colorado Railcar DMUs can provide over locomotive-hauled trains for various passenger capacities. This validates previous work that has shown that DMUs can save transit agencies millions of dollars in operating costs.

The study concludes that:

  • DMUs may save as much as 28% on variable operating costs, which are defined as the sum of fuel, maintenance, and operating crew costs
  • When DMUs cost more to purchase than traditional rolling stock, the difference can in several cases be paid back with as little as 2 years of operating cost savings
  • Owning DMUs is like buying your rolling stock at as much as a 69% discount, when the DMUs’ lifetime operating cost savings over locomotive-hauled trains are taken into account.

DMU Provides Significant Operational
Savings Over a Commuter Locomotive

FUEL CONSUMPTION COMPARISON

Locomotive Hauled Commuter Consist:


Fuel consumed during typical round-trip commute (60 miles):
120 to 180 gallons
  • Locomotive engine produces 3,500 hp
  • Locomotive weighs 300,000 lbs
  • Locomotive consumes 2 to 3 gallons per mile
DMU Commuter Consist:


Fuel consumed during typical round-trip commute (60 miles):
     
30 to 40 gallons
  • DMU engines produce 1,200 hp
  • DMU weighs 175,000 lbs
  • DMU consumes only 1/2 gallon per mile

Note: During testing at the TTC Pueblo, Colorado, the DMU exceeded fuel efficiency expectations dramatically by achieving two miles per gallon.
