Extra Luggage Racks For Lumo

The title of this post, is the same as a small article in the November 2023 Edition of Modern Railways.

Thiese are the first two paragraphs.

Lumo is to remove eight seats from each of its five Class 803 EMUs to make way for additional luggage racks.

Two seats will be removed from four of the five vehicles in each unit to make space for the luggage racks. The move has required a variation of Lumo’s track access agreement, with the Office of Road and Rail, which as originally approved specified that each train must have 400 seats.

The article also states that Lumo has stopped carrying bikes and the bike areas are now used for luggage.

Batteries For Lumo?

The article finishes with this paragraph.

Lumo celebrated its second birthday in late October and was also set to mark the carriage of its two-millionth passenger. It is understood Lumo is interested in augmenting its fleet, such has been the success of the service; while many operators favour bi-mode units, Lumo is proud of its all-electric credentials so straight EMUs are still preferred, although the possibilities of including batteries which could power the trains may be pursued (the ‘803s’ have on-board batteries, but only to provide power to on-board systems if the electricity supply fails).

I find this development very interesting.

As an electrical engineer, I’ve always believed that the emergency batteries in the Class 803 trains are very similar to the traction batteries that Hitachi are developing for the Class 802 trains.

• One design of battery must surely save time and costs in design and testing.
• The difference between the two batteries might be only software and the total capacity of the lithium-ion cells.
• In service testing under real operating conditions can be carried out in Lumo’s Class 803 trains.
• Traction and emergency batteries would be interchangeable, so some operators, who didn’t always need traction but wanted emergency on-board power could be setup as required for the route.

If traction batteries gave the train a range of perhaps 15-20 miles, this might well be enough range, for the train to get through or to the next station, if there was to be an incident like catenary failure or a derailed freight train blocking the line. Obviously, Lumo will have records of all external failures that have affected them.

Consider.

• I have calculated that Peterborough and Doncaster via Lincoln is 88.5 miles.
• I also believe it is likely that in the future, there may be some electrification at Lincoln to charge battery-electric trains.
• Lincolnshire is flat.

Would it be possible for Lumo trains to use a single traction battery to take the Great Northern and Great Eastern Joint Line to get round engineering works on the East Coast Main Line?

What Length Of Trains Could Lumo Run?

In Ten-Car Hull Trains, I talked about Hull Trains running ten-car trains to Hull.

I would expect that all Lumo’s stops are possible with ten-car trains.

As the trains are all Plug-and-Play, Lumo could either run pairs of trains or perhaps lengthen all trains to any size between six and nine cars.

Could Lumo Piggy-Back An Aberdeen Service On An Edinburgh Train?

The line between Edinburgh and Ladybank is being electrified and Ladybank is just 91.4 miles South of Aberdeen.

• A pair of Class 803 trains could leave King’s Cross running as a ten-car formation.
• The leading train would be a Class 803 train equipped with a traction battery.
• The trailing train would be a Class 803 train equipped with the normal emergency battery.
• Aberdeen passengers would get in the leading train.
• The train would run as normal to Edinburgh.
• At Edinburgh the two trains would split with the leading train going on to Aberdeen and the trailing train getting ready to return to London.

The train going to Aberdeen would need sufficient battery range to cover the 91.4 miles to Aberdeen, where it would recharge to make the journey back to Ladybank, Edinburgh and the South.

What About Inverness?

Dunblane is the nearest electrified station to Inverness, but it is 146.2 miles away over a route with lots of steep climbs.

I doubt that a battery-electric train could handle that route.

Conclusions

Luggage seems to be getting more of a problem on trains and buses.

It does appear that a very innovative battery philosophy from Hitachi is emerging.
