Qualifying Nouns with verbs question
Im using Integrated Genki Books.

So in the book to qualify nouns with verbs is (for example)
- めがねをかけているひと。
Which uses the short form for the verb before the noun...

But I found one that is using the verb stem and not it’s short form. I don’t know if both are correct or what? The sentence is this
— 京都行き電車（きょうといきでんしゃ）ps I don’t know any kanji so it will be helpful if you give me the kana too.

Answer

京都行き電車 is not verb + noun.
This is just noun.
This is used like this example.
Ex:私は(くるま)に のります。
     私は(京都行き電車)にのります。

Answer

京都行き電車   is a compound noun which consists of two nouns, 
”京都行き” , a noun made from a verb, and ”電車", a noun.

”行き” is a 連用形(RENYOUKEI) of a verb "行く“　(It is not a stem. The stem of 行く(IKU) is "IK")
連用形 is often used as a noun.

※ The structure is same as "駆け込み乗車“, which consists of 駆け込み（かけこみ）and 乗車（じょうしゃ）
※ 京都行き is also a combound noun.
