Since I've been travelling a lot the last couple of months I've not been
keeping you up to date with the exciting developments in the east of our great
continent, which I know will have left many heartbroken - but I'm delighted to
make up for it with some snaps of our new Astra Imperio trams that have
started appearing in Bucuresti, after my first ride on one this afternoon:

<https://imgur.com/a/OlHP6FA>

They're actually rather nice. Made in the local (well, western Romanian)
carriageworks Astra in Arad, they seem well put together, ride well on our
terrible track, and most important of all - the air conditioning works. With
my outdoor thermometer currently reading 41C, this is important.

Technicallly they're quite interesting; 4 segments/3 articulations, none of
the articulations are supported by bogies (sorry, no Jacobs' bogies here) -
each segment has one bogie, with the front and rear bogies in a set powered.

The trams are 100% low-floor throughout, with passenger seating above both the
powered and unpowered bogies. To achieve this, the motor bogies are powered
stub axles; each bogie still has two motors for four wheels, but the motors
are arranged longitudinally such that each motor drives the wheel in front and
behind; they are provided by Siemens Mobility and if not identical are clearly
related to their SF30C (based on eyeballing alone):

One other notable feature is it's the first time I can recall a STB
(Societatea de Transport Bucuresti, nee RATB) vehicle having a custom
moquette... Or indeed a cushion of any description, for that matter.

I got a warning that the post may contain erotic imagery! Well, if trams
turn you on…

So was I. I was severely disappointed, I tell you.
