Chicago South Shore & South Bend Railway "Little Joe"

Chicago South Shore & South Bend Railway "Little Joe"

The Railway Age has an interesting examination of negotiations between the US railroads and power companies. The idea is the the railway right of way would be used for transmission lines in return for electrification and low cost power for trains.  This is tied to the idea that if there is to be a high speed passenger network then it would have to be electrified. The new power lines will be needed to connect new power sources such as wind farms to the grid. But freight trains could also be hauled by electric locomotives. Indeed the story is illustrated by the image of a Chicago South Shore & South Bend Railway electric loco hauling a coal train (“Little Joe”). BC also had it own electric freight railway to haul coal to the coast from Tumbler Ridge – and one of the most inexplicable decisions surrounding the sale of BC Rail was the scrapped that system and its locos (except one pictured below preserved at Prince George).

North American freight trains are mostly hauled by diesel electric locomotives – and one of the ideas floated in this story is that  of dual power locos: the same electric motors could be powered by the on board diesel or the overhead wire. This would also, by the way, capture the energy used to brake trains – currently dissipated as heat – by using the same motors as generators with power being fed back into the system. SkyTrain and the trolleybuses already do this.

“A version of the latter, the ALP-45DP, is currently being built for New Jersey Transit and Montreal’s AMT by Bombardier. Such a locomotive would give a Class I the flexibility of operating trains in electrified and non-electrified territory without changing power.”

The railways identified as most interested are BNSF (who have a line into Vancouver) and Norfolk Southern. Notable by their absence – CN and CP.

  1. I would imagine that railroads with steep gradients would opt for electric traction, as it would be far cheaper than diesel. In a time of peak oil, one wonders why more railways are not looking to electric operation?

  2. CP should be all over electrification with the steep gradients and long tunnels they have in eastern BC. CN was essentially given BCR so I’m sure they’re waiting for a similar handout before they say a word about electrifying any lines.

    While I agree that scrapping the electric locos instead of repurposing them was a waste, but there was no point keeping 132km of 50kV lines going to what soon became a ghost town.

  3. I think I remember being on a VIA train (in 1987) entering Montreal’s central station when they announced that the lights would dim because they were switching to electric power.

  4. Yes there are electric suburban train services in Montreal

  5. BCR 6001 is in Prince George BC.
    The electric line at Tumbler was unsustainable – Units suffered from various problems – traction motors had to be replaced three times. Etc

    Electric trains were picked for no ventilation would be needed in the two long tunnels. Government grants were being given out at the time as well.

    It cost 31 million to install the lined and substation in 1980s money.

    However there was a lack of tonnage and the electrics cost a fortune to run and were suffering from break downs.

    The average electrical demand charge in the 1990s was 90,000$ a month – by 1996 the line was unsustainable with electric units.

    October 1 2000 BC Rail went to full diesel operation of the line.

  6. Dual Mode Locos are a rare breed. I can imagine the cost on loco to be pretty high.

  7. The Southern Railway Region of British Rail in the UK, had dual mode Bo-Bo Electro-diesels. 750 Volt d.c. 3rd rail (1,600 hp) or diesel (600 hp).

  8. The Little Joe was actually owned by the Chicago South Shore & South Bend Railway. The interurban bought three numbered 801-803 and operated them into the early 1980’s.
