On its test run it reached Zagreb in 5 hours and 4 minutes, and took 650 m to stop.

Ugly af and not really that impressive.
Meanwhile this [thing](https://en.m.wikipedia.org/wiki/LNER_Class_A4_4468_Mallard).
sadly, it has many antiaerodynamic features, rivets standing out to increase air resistance, no front to back sloping, no wind tunnel testing…
1936 had many streamlined trains introduced in europe… It was a golden era, really.

In 1932 the diesel-electric DRG Class SVT 877 “Flying Hamburger” had a top speed of 160 km/h, in 1930’s Luxtorpeda reached 140km/h in Poland, soviet 2-3-2K had 150km/h in 1938, Netherlands had in 1934 the Materieel 34 (DE3) in 1936 a three unit reached 140 km/h, During test drives in 1935, the SVT 137 “Bauart Leipzig” set a world speed record of 205 km/h, , the Tatra 68 reached 148km/h during testing, On 6 December 1937, an Italian ETR 200 made a top speed of 201 km/h.
On 11 May 1936, the DRG 05-002 set the world speed record for steam locomotives after reaching 200.4 km/h
Golden era, really.
While I respect their accomplishment, it’s pretty ugly. Here’s the Baltimore and Ohio “Royal Blue”, from the same year. [Link.] (https://commons.wikimedia.org/wiki/File:B%26O_Royal_Blue_in_1937.jpg)
