That curve has radius of around 850. With maximum cant height that should allow for speeds up to 145 km/h for classical trains (depending on national rules) and possibly up to 160 km/h for tilting trains. Next curve has radius of 400 m, that should allow speeds up to 100 km/h.

It could be slower as the train was approaching station. The second one was passed more slowly. I guess it was 60-80, but the first one was passed really fast.

I"m not going to calculate the curves's radius, but looking on the map I see that just few hundred meters west there is another, even tighter, curve, followed by a railway station. The second (western) curve plus that station cannot be taken with 160 km/h. Maybe the train goes with that speed on the section south-east of that curve (to Bratislava), but it certainly doesn't take the curve you indicated with 160 km/h.
The speed in that curve is limited to 70 or 85 km/h depending on the train. The first curve is then 130 km/h. The station should have 110 km/h trough speed if I am not mistaken.

If there are 2 consecutive curves with different designated speed, it's obvious that the train will go as fast as the "slowest" curve allows. There isn't too much gap between them for the train to either accelerate 100 -> 160 km/h or brake 160 -> 100 km/h (depending on it's direction of travelling), so it's clear that he won't pass with 160 km/h in that area.

If the train arrives at the station from SK it decelerates from 130+ to 130 and then to 70 (85).

If the train leaves the station to SK it accelerates from 0 to 70 (85) and then to 130.

Most of the track should be then 160, but I am not sure of that.

I don't think that there are many trains that ere not stopping in that station as it is a major hub. Railways from 4 directions meet there.

This video is from driver's post, it is accelerated though :-(. But the first curve is not that close to second one. I think there is enough space to slow down or accelerate.

They couldn't say it in Romanian??

(Oh, I see now. It's a joke. Obviously haven't had enough caffeine today.)

(Just don't mention 300 km/h tracks for ICE because German highspeed network is kinda backward comparing it to French, Spanish and even Italian)

270 km/h (Paris-Lyon) is not that much faster than 250
About those railway curves I don't have enough data, I just calculated maximum design speeds for known radii. It is possible to have 100 km/h in first curve and 160 in second but it is clear from posted video that real speed is lower.

The nicest place IMHO to have a meal with amazing and incredible views is on board an airplane flying in clear blue skies from the Mediterranean all through the alps to Northern Europe, while comfortably sitting and enjoying .

until turbulence strikes or until when at the airport your luggage reminds you about Earth's gravity but a peaceful flight can be enjoyable.

A popular Serbian pop and folk singer sings in... Chinese?!
https://www.youtube.com/watch?v=LAFqfUH0_Ho
But this is not the first time a Serbian singer has attempted to sing in a language other than Serbian and English with hilarious results:

They replaced the sign at the station here and they got a bit carried away with the bilingualism:

In Canada such is popular, like "information / information"

But I am more curious about the "waste pedestrians"

I remember couple years ago some people and newspapers in towns that had been fitted with Occitan signs in France were actually complaining about, or even removing, some of the signs because Occitan had never been a local language there.

I remember the same with Breton and the infamous Saozon-Sevigneg

There were complains once in Trieste, when they installed a temporary sign (it said "road closed" or something like that) written both in Italian and Slovenian, because Trieste city is not bilingual, so the sign had to be in Italian only!
