I Sighted This Vectron At Karlsruhe: A Dual Mode, Which Can Move Either With Its Diesel Engine Or Getting

Saint Servan and the Solidor Tower

On the right-hand side of the Rance river, just before the fortified city of Saint Malo on the estuary, is the smaller town of Saint Servan. In fact, it technically isn't a town anymore, it was absorbed by Saint Malo in the 1960s. But for most of history, there was a stark contrast between the two, as Saint Malo fiercely proclaimed its autonomy several times. Hence the Solidor Tower.

Consisting of three tightly-bunched round towers and their connections, the Solidor was built in the 14th century by the Dukes of Brittany as a means to control the Rance estuary, against the rebellious Saint Malo if needed.

Like other fortresses, such as the Bastille in Paris or the towers at La Rochelle (another time maybe), its strategic value soon dwindled, and it seemed best-suited to serve as a prison or as storage during the late 18th-early 19th centuries. It has been an officially classified monument since 1886, and had housed a maritime-themed museum since 1970, though this appears to be in limbo and I can't find the tower's current function.

A walk along the coast on the West side of Saint Servan will reveal a bit more history: an old lifeboat station, a small tower in the sea that serves as a tide gauge... further up, a WWII memorial with the remains of concrete bunkers, and further along, a view of Saint Malo. It's a worthwhile detour for people visiting Saint Malo, especially if you're concerned that the city centre will be too crowded. But I think I remember parking here wasn't easy either; on a nice day, the locals who don't want the hassle of "intra-muros" would come here.

A potential unfulfilled: the Intercity 225

As I had some time to wander around before catching the Eurostar back to France, I checked out the trains at King's Cross station. To my slight disappointment, there wasn't a huge amount of variety on display: Azuma, Azuma, Azuma... They're nice trains, don't get me wrong (built by Hitachi, using the same base as JR Kyushu's 885 series), but that's all there was. Still, I decided to check out all the platforms, and, at the far end, hidden behind an Azuma, there it was.

The star in train books during my childhood was the Intercity 125 or High Speed Train (HST), a 125 mph-capable Diesel-powered set, which, I think, still holds the world record for the fastest Diesel passenger service. I would have loved to see one when visiting England, but this was just as good. In fact, I had seen it out of the window while riding into London, taken a crappy photo and thought "oh well, never mind", only to see it had followed us in.

In the early 90s, the Intercity 225 was touted as the next big thing: all-electric, capable of running at 225... km/h (that's 140 mph, using different units was admittedly a bit disingenuous), designed to receive a tilting mechanism later on, completing the Advanced Passenger Train's redemption arc. What could go wrong?

Not long after the introduction of the Intercity 225, Britain's railways were privatised, with the typical lack of ambition for service that it brings. No private company was going to invest in the infrastructure and upgrades to allow the train to reach its full potential; meanwhile France and Germany were expanding their 250-300 km/h networks. Instead, these trains were limited it to 125 mph - the same as the HST, just on electrified lines. Worse still, it was one of these sets that met with the consequences of the privatised rail maintenance's culture of corner-cutting and outsourcing, on a broken rail at Hatfield in 2000.

From the outside looking in, I'm left with a bitter sense of "what could have been" for this train. Perhaps a rail fan from the UK could say more about what they feel the Intercity 225's legacy would be. At least its successor, the Azuma, has the fact that it's bi-mode (Diesel and electric) to shout about.

Still great to see one and its "so 90s" design in the flesh! LNER have also given the trains their original livery back, except with a burgundy main body colour instead of the original graphite grey, while the locomotive was in a special commemorative livery for the Battle of Britain Memorial Flight.

First Christmas Market of 2024

Not as early as Ebisu, but still, just over a month before Christmas, I got to my first market on 23 November. On our way to Thann with two fellow hikers, our train was delayed and we had half an hour to kill in Mulhouse. I know the city centre is quite nice, so we went there, and found the Christmas market!

Place de la Réunion is gorgeous with its trompe-l'oeil facades (walls that have bricks, columns and other ornaments drawn on them) and church, which, unusually for a major French town, is a Protestant temple. It's extra-special with Christmas decorations, such as the town hall seen above. The water mill wheel is the emblem of Mulhouse, referencing the name's origin, Mülhausen, "mill house".

Neuviller-la-Roche

Quick post today - just a few views of climbing out of the village of Neuviller-la-Roche in late March 2022.

Hikawa Maru at sunset

Moored permanently at Yokohama as part of a park and seafront promenade, is the ocean liner Hikawa Maru, built in 1928-1930. After life as a passenger ship and a hospital ship during World War II, it survives in impeccable condition - the paint is vibrant and there's hardly any rust to notice.

It is a museum ship and a protected monument, as evidenced by the banners:

(happy captain face) 船内を見学できます: you can take a tour inside the ship

重要文化財 日本郵船 「氷川丸」: Important Cultural Property, Nippon Yûsen ship Hikawa Maru

Obviously, I was too late to be able to visit the ship. I had arrived at Shinagawa late afternoon and was hopping over to Yokohama for a sunset walk-around and dinner.

I'm bringing it up because Mike Brady featured the Hikawa Maru on a recent episode of Oceanliner Designs about ships that avoided destruction and that still survive.

Where I grew up (initially): Great Chesterford

Going back to Great Chesterford with my current eyes was quite interesting. I hadn't realised (as no 6-year-old would) how pretty the village centre was, with many charming houses and thatched cottages. The nearest town, Saffron Walden, is even better, but I'd need to go back and visit properly. This time, we just passed through there to go to the shops - and pick up a bunch of biscuits and sweets I remember from my childhood!

Said sweets and biscuits are very nice, of course, but also a tad underwhelming. I remember feeling disappointed by the size of Party Rings the last time I bought some, and I had a similar sense of underwhelming when passing near the school. The wall along the street was much higher in my memory, as was the hill at the back of the playground - in my mind, it was a proper hill! But take into account the fact that I was so much smaller back then, and it all checks out, really!

The old school building itself was apparently built by a single person between 1845 and 1849. Chesterford has a very rich history, dating back to Roman times (and if nothing else on the topic, I remember dressing up as a Roman at school once), and the church dates back to the 13th century. The village's biggest claim to fame is probably having been the home of Germaine Greer, a feminist author from the 1970s, for a few decades.

Schirmeck castle

Overseeing the valley of Schirmeck, the castle, built for the Bishop of Strasbourg in the 13th century, is a short walk and climb from the town centre. As it was designed to protect a corner of the territory, that's apparently where we get the term: Schirm'eck. It was defeated by the Swedish during the Thirty-Years War, with some of the stone from the ruins being used to build other structures, such as the church.

Today, there's obviously not much of it left, though a square tower was restored and houses a small museum (closed when I visited). The Yoshi art was probably not part of the original episcopal aesthetic...

Seaside sunset at Le Havre

Enjoyed a nice weekend away with long-time-no-see friends in Normandy. The rain cleared throughout Saturday, giving us the opportunity to get out and watch the sunset from the "End of the World" beach, along the coast from Le Havre, out of view from the industrial port.

After the Sun had set, the layer of cloud on the horizon seemed to thicken, giving a very curious palette of shades of grey. There was still some light in the sky, but the ships waiting in the Channel floated against a somewhat uncanny background. The following are colour photos, I swear...

On the JR Nara line

Uji city and the the building on the 10-yen coin can be accessed by train from Kyôto by going roughly a third of the way to Nara. Other famous sites near the line are Fushimi Inari Taisha (Inari stop), and the studios of Kyoto Animation, famous for the music and sports anime K-On and Free! (Kohata stop).

The most recent type on the route is the 221 Series, and it's already getting on a bit, introduced in 1989. It won one of the Japan Railfan Club's two main new train design awards, the Laurel Prize, the following year. The 221 is used on the fastest Miyakokji Rapid services, which do the Kyôto to Nara run in under 45 minutes.

Green 103 Series sets can also be seen. This is the oldest type still in active JR service (if not, it's close), as it was introduced in 1963. In 2016, when I first visited Japan, I was living near Paris, and some Métro and suburban lines were running trains of a similar age, if not older, and these were atrocious in hot weather - no air conditioning, and ventilation only provided by opening windows! The RATP MP 59 used on Métro line 11 was stinky to boot; it was withdrawn just before the Games, no wonder! Point is, the 103 doesn't have air con either, but is at least trying...

Sangaku Saturday #13

Last week, we uncovered this configuration which is also a solution to our "three circles in a triangle" problem, just not the one we were hoping for.

This is something that happens in all isosceles triangles. Draw the inscribed circle, with centre B, and the circle with centre C, tangent to the extended base (ON) and the side [SN] at the same point as the first circle is. Then it can be proved that the circle with centre A, whose diameter completes the height [SO] as our problem demands, is tangent to the circle with centre C.

But that's not what I'm going to concentrate on. Despite this plot twist, we are actually very close to getting what we want. What the above configuration means is that, returning to the initial scaled situation with SO = h = 1 and ON = b, we get

Knowing a solution to a degree 3 equation is extremely powerful, as we can factor the polynomial and leave a degree 2 equation, which has simple formulas for solutions. So, to finish off, can you:

1: prove that

2: solve the equation 2x²-(s-b)x-1 = 0, and deduce the general formulas for p, q and r that fit the configuration we are aiming for;

3: test the formulas for an equilateral triangle, in which s = 2b.

This last question is the one the sangaku tablet claims to solve.
