Musing about bumpy ride quality on trains this morning
As ever I am on a Régiolis EMU to Paris this morning - an Alstom design, now owned by CAF
These trains have a rather jerky, bumpy sort of ride, and the suspension makes clanking noises all the time (not just today)
Are the jabobs bogies between carriages poorly designed?
Wdyt @hopla @wrzlbrnft ?
Waving metaphorically to @ffeth at Sens

@jon (the design of the Coradia Polyvalent is still Alstom and AFAIK so is the software maintenance, but the assembly and hardware maintenance is contracted to CAF Reichshoffen as part of the Alstom-Bombardier merger deal -the latter having an assembly workshop in Crespin)
The Régiolis' suspensions are kinda "harder" than those of the AGC, they usually hold rather well very bumpy tracks such as the Bruyères - Arches line (whereas on AGC one can feel sometimes metal hitting metal in the suspensions). That is, as long the air pressure is nominal, the air cushion in good state and the train not overloaded. I'm unaware if there's a difference in design between bimode (+fuel weight) and pure electric in that aspect. I'd need to experience it to judge if that's abnormal noise/movement ^^

@hopla I am not sure the AGC is much different, or at least not better! Those also rock sideways more!

@hopla Also it must be said that this line ought to be an Intercités really. The Régiolis does a steady 150km/h for long sections here. And it is not really designed as that sort of train...

@jon rollercoaster ride at a fraction of the cost of an Europa Park ticket
That said, I'm thinking of something: "track deformation slow creep": when a train track deteriorates over time but just slow enough so that train drivers doing it daily don't immediately notice something abnormal developing and thus don't report it for the infra operator to go check the geometry with measurement engines outside scheduled audits. (the budget to do any fixing about it is another story) -

@jon the Coradia Liner wouldn't differ much in terms of design on that aspect I guess.. but as newer intercités rolling stock there's Oxygène (entirely CAF design IIRC, I know relatively little about it except it's to be built in Reichshoffen too)

@hopla CAF‘s Media Distancia EMUs in Spain are horrid. I hope they install better suspension!

Made it across Paris in one piece
The city might have solid bike infrastructure, but damn many cyclists here are annoying, or have death wishes, or both

And while Paris Nord is often associated with nasty train boarding experiences, it is an amazing station if you have time and calm to appreciate it

C'est vrai!

@jon "Monsieur vous ne pouvez pas attendre sur les quais!" is my typical gare du nord experience

@jon oh they better... Or else: no 200 kph.

I meanwhile wondered if SNCF Connect has finally put their problem of their lack of international booking right... so I tried Paris - Mainz
Type Mainz into DB and it gives you Mainz Hbf as the first option in the search
SNCF Connect calls Mainz Hbf "Mayence (Mainz)" but drops Hbf. Put Hbf and it gives you Hbf (Ersatzverkehr). What?

And if you put Mainz and choose "Ville" from the list, not "Gare", it gives you routes to Mainz Römisches Theater, changing at Bad Munster am Stein
Obviously
️I presume because Römisches Theater is closest to the geographical centre of Mainz?

@jon Fact.
