Szia. Jó reggelt!

Oh, you know I love learning Hungarian!:)

By the way, the picture is really, really száp.

A little of history about Budapest...

I`ve read an article about Budapest and decided to translate the (you should use the indefinite article "a" here instead of the definite one) part of it into English. 

There are (You cannot have two conjugated verbs in one simple sentence.) trolleybusses appeared in 1949 in Budapest. (Logicwise, it would be better to say "in Budapest in 1949", because the time is the information you are supposed to emphasize here and whatever needs to be emphasized comes at the end of a sentence.) The first one got number 70 at once, because this ("that" would be a better option. It was a long time ago.) year was (the) celebration of (the) 70th anniversary of Stalin. And now there are no trolleybuses (you use "busses" in the beginning sentence, but here you are using the alternative plural form of the word "bus". You should always use one fixed plural form for a word all through the same article to maintain consistency) before number 70 in Budapest.

I hope you will like this fact of history.
