I don't think this has been mentioned on this group before. Add 10-15%
to that and Inverness to Wick becomes possible.

That record-breaking distance is 25% higher than Inverness-Wick. The
reliable, operational range will be much less, of course.

I suppose the solution would be to have 2-3 top-up stations en route, such
that even if one isn't working, trains can still make it. They could use
the Vivarail charging system, and only need a short charging stop. Maybe at
places like Tain, Helmsdale and Thurso?

Wikipedia quotes 161 miles 11 chains (259.3 km) which is bit more than
the record breaking distance. Did you use the road distance - 104
miles according to Google Maps?

No, the rail distance of 174:31, which is longer than the road distance:

Plus, you have to take the altitude differences into account. Berlin -
Warnemünde is essentially flat, plus it's 40m downhill (which yould only
make a small impact).

If we are looking for nodes on the power network, Brora is about
halfway, and I'd ignore Wick versus doing Thurso in both directions.

On the other hand, it's an awful lot of faffing about for four services
(three units?) a day in each direction.

But what about maintenance costs? Presumably a battery pack and electric
motors require much less attention than Diesel engines.

Would there be a problem extending the range of such a train by inserting
an extra vehicle packed full of batteries?

OK so taking that figure it's about 280km which as I originally said
is more than the 224km of the world record.

"That record-breaking distance is 25% higher than Inverness-Wick" -
Did you perhaps mean that sentence to read lower?

Not that it matters! I wondered when the West Highland, Far North etc.
were shown as never being electrified what the "alternate" solution
might be in the absence of Bionic Duckweed. Perhaps Battery solutions
are closer than I (we) thought!

It's an issue of scale. All this new equipment for just three units (if
I've counted the diagrams correctly).

If it was three hundred, it'd be different.

With or without corridor connections?

Careful about the weight.

Yes, sorry, I meant that the Wick-Thurso distance is 25% higher than the
world record distance.

Yes, could be, but only for low speed trains.

It might be better to have an extra charging point on the route, as
batteries are heavy, expensive, take time to charge and have a limited
life. Of course, thanks to all the automotive R&D, they're improving every
year. Cars with realistic ranges of >300 miles are available already, and
>400 miles isn't far off.

The other alternative for longer routes is hydrogen. It costs more, but
would reduce or eliminate the need for mid-route charging points. And, with
so much local wind power, hydrogen might be readily available in the far
North.

Was the record run non-stop, or did it make numerous intermediate stops?
That is unclear from the source reference. Making numerous re-starts
would be expected to consume more energy, and reduce the operating
range. Even so, it looks promising if the battery purchase & renewal
costs are affordable.

Although what you'd really need is hydrogen bottling plants in the far
North. Is there enough demand from three short trains shuttling back and
forth, to make a return on such an investment?

If it was a deliberate, record-breaking attempt, it was probably non-stop.
That's why the range was so much higher than the normally working range
(80km).

Another completely different route to net zero is synthetic fuel, which is
effectively another way of using solar power (eg, turning Brazilian sugar
cane into ethanol for cars). That's the likely solution for long distance
aircraft, but could also work for long disance trains on non-electrified
lines. But it'll be significantly more expensive than petro-diesel.

Small, electrically-powered hydrogen production and compression (why
bottling?) plants are simple enough. I think that's how the small number of
existing hydrogen fuel stations work. Of course, the plant would also be
used to refuel heavy road vehicles and railway freight locos, not just a
few small passenger trains.

As for making a return on the investment, let's not kid ourselves that any
of these zero carbon solutions will be cheaper than existing ICEs. They're
favoured for other reasons, and will be a lower priority for
decarbonisation than transport and heating in large cities.

Also has the crucial disadvantage in that it takes agricultural land out
of food production.

Yes, assuming it's not done at sea. Instead of fish farms there could be
synfuel feedstock farms, perhaps cultivating some fast-growing GM kelp or
sea weed (ie, bionic duckweed). But those are years in the future, and may
never happen.

It depends on the political pressure for true net zero. That's currently
high, but will probably drop very soon, when our leader and her big and
small dogs are evicted from Downing St. None of her likely successors are
so keen on it.

Net Zero doesn't mean banning every form of fossil fuel (however small
and insignificant). That would be GROSS zero.

Yes, Inverness and Wick are both close to sea level, but there are hilly stretches in between.

Another consideration is that these trains run through remote areas that can get blocked with snow or other bad weather,
so you need to have quite a large reserve fuel supply on board. You can't design a system where they are routinely
running at low charge as they get to the next charger.

Or to wire some (short-ish?) sections of the line, maybe on rising
gradients, to provide a boost to both the batteries and to the train
itself.

That would be the normal solution if the trains are designed for part-time running under the OHL, for example, with the
suggested battery version of the bi-mode IET (batteries replacing the diesel engines). But that may not be the case if
they're converted DMUs.

Yes. I tool the OHL idea from the FLIRT description. Obviously other
train systems would work differently.

How do you get the power to those sections of line? It's pretty isolated
landscape.
