Whoa! I know that one -- it is "Shinagawa". I know this because my hotel was at that train station in Tokyo on a trip in the early 90's, long before signage in English was common in Japan..
Two or three of something is a pretty common pattern in kanji. Two basically implies "several", while three implies "a fuckton". Two suns, for instance, is "bright". Three suns is a sparkling crystal.
Languages are weird, man.
