Alstom’s Coradia iLint, the world’s first hydrogen-powered passenger train, will demonstrate green traction in Quebec

Coradia iLint will carry passengers in a commercial service demonstration on Quebec’s Reseau Charlevoix network, at the heart of a UNESCO-listed biosphere reserve, during 2023

Interesting. I hope as part of the demonstration they measure how much electricity (and its cost) is used to make the Green Hydrogen and compare that to how much is required to feed to the train directly with catenary (and the cost of the catenary). Hydrogen may make sense it places where catenary isn't feasible, but it isn't a complete replacement for catenary.

Depending on the distance battery power would be better.

Yeah....not without fast charging on the way. Diesel hybrid is a proven technology.... Using electricity to make hydrogen and then burning that to move a train is not efficient.

I saw that unless you can burn it in an internal combustion engine and not a fuel cell. Cummins is already working on releasing hydrogen gas conversion engines. https://www.cummins.com/news/releas...-inc-debuts-15-liter-hydrogen-engine-act-expo

You would need multiple to operate a train. You could possibly use it as a genset and have batteries onboard but again diesel hybrid is still easier.

They could build hydrogen generating systems at stations but then you need to store it, super cool it, blah blah blah.

The problem with burning hydrogen (rather than using it in a fuel cell) is that it is no longer zero emission, since when a nitrogen and oxygen gas mixture (the two most common gases in air) are superheated, they produce nitrogen oxides (NOx). In fact, since hydrogen produces more heat when burned than gas or diesel, it will produce more nitrogen oxides.

Are you sure about that?
HYDROGEN INJECTION DIESEL ENGINE SYSTEM
Independent testing has shown the addition of hydrogen provides a cleaner burn and reduces harmful emissions by up to 80%. The technology includes sophisticated electronics which are demand responsive to hydrogen flow to optimise engine performance.

Hydrogen injection has been around since the early 1980s - hell, Hamilton had a bunch of buses set up for it before they finally decided on using Natural Gas - but all it does is add a bit of hydrogen into the combustion cycle of an existing diesel-powered vehicle.

But roger said it's more harmful, but the manufacturer says otherwise...

That's because the two of you are talking about two totally different things.

Roger is talking about hydrogen combustion - burning nothing but hydrogen.

The thing that you quoted is adding a small amount of hydrogen to a diesel engine. Whatever added emissions from the burning of the small amount of hydrogen are offset by the reduction in emissions from the burning of diesel. Or at least, they were at that time. I don't know if that's still the case with modern engines.

Very sad.

Good Afternoon Everyone,

On the afternoon of Monday, February 13, the GHRA was made aware of a break in which had occurred on both our coach, 3216, and caboose, 436994 over this past weekend.

Vandals appear to have entered the floor, currently partially removed for restoration/installation of new steel and plywood. Every last piece of wire has been stripped from the coach, electrical panels and controls removed, copper team-heat pipes removed, brake pipes cut, some metal curtain track assemblies removed, water pump and boiler components removed, new steel flooring, among numerous other items. An itemized list is currently being put together as damage is likely near the twenty thousand dollar mark.

Damage to the caboose was limited to a slightly damaged lock, cut chain, and a kicked-in plexiglass window. One thief also defecated in the cupola, which has been cleaned out. All cabinets had been searched and items left stacked for later retrieval by vandals. These items are currently being held by members for safekeeping.

Due to the high financial cost of damage from this break in and the smaller one in August 2022, which had an estimated eight thousand dollars of damage, we are exploring our options with our insurance broker. With this being a repeated issue to our equipment, along with all businesses immediately surrounding our site, options are being discussed with the Guelph Junction Railway as to what our best options are for security.

One likely possibility is shoving our equipment a few hundred feet closer to Elmira road, making it very visible to passersby. Another possibility could be securing the coach at a different location or at a customer on the Guelph Junction Railway. The caboose and baggage car have been located here since December 2014 with only one incident of teens breaking in on weekends using it as a clubhouse (summer 2017). Vandals are recognizing the value our coach holds, attracting them to our site.

Presently two motion activated trail cams have been setup, one in each the coach and caboose. If the thieves do return for anything else we will be notified instantly of movement in either car.

This is a setback with our restoration, however we have made good progress. Our coach had working heat, lighting, and final air conditioning parts were being installed to complete that system. The former smoking section and snack bar, making up roughly 1/3rd of the car, had been gutted and the floor removed for rebuild. Window seals were also in the process of being replaced to stop water from leaking into the car. Pending our options to secure the car and reclaim some financial loss we will be looking to get back to this work as soon as possible. Both the Guelph Junction Railway and Goderich-Exeter have expressed interested in a tourist train once the restoration is complete.

A report has been filed with the Guelph Police Service. A journalist from GuelphToday has reached out for a last minute interview which was conducted this morning. Similar break ins have been happening throughout Guelph in recent months.

We will keep everyone posted as this develops. If members wish to assess the damage the equipment can be opened, however please use caution as much of the floor is open.

Cheers Everyone,
GHRA Executive
