Zenus, some ideas for possible chrono events:
Since 5th July 2014:
- for first time in history 18m buses take place
- it was not possible due to Zoologická zahrada boarding stop where driver cannot see doors in trailer
- new SOR NB18 buses have CCTV so this is resolved, no other 18m buses except SORs are allowed on the line
Since
6th October 2014:
- line 112 goes across new Trojsky bridge but only when heading to Nádraží Holešovice (previously across the Most Barikádníků in both ways)
- Pelc-Tyrolka and Jankovcova stops are canceled in direction Nádraží Holešovice (only)
- in direction Zoologická zahrada/Podhoří the Pelc-Tyrolka stop is still functional but Jankovcova is not (was not even before, since 2013 i guess), buses go through
- Trojská stop is now mandatory (previously was request stop as trams did not operate track across the bridge and only substitutional tram was available - see
this picture of Trojská street uphill)
Since
11th November 2014:
- from November to (assumed) April only 12m buses in operation due to low demand
Since
21st February 2015 (temporarily):
- line goes across the Trojský most bridge in both direction due to construction works (skipping Pelc-Tyrolka)
- second stop Nádraží Holešovice is established where transfer to tram line 17 is available, probably directly in tram station, I'll take a photo when it's actual
