All I remember is that it was a show for kids which took place in an art studio, there was a women who played a keyboard and had a computer, a black man who was a painter, and they had a robot. There was a balcony where the black man painted, and another man who dressed up in costumes. And there was a train that would go through the balcony to deliver drinks to the balcony. If anyone remembers this show, pleeeease let me know. This is killing me because I can't remember thanks!:)

Sounds kind of like the Reading Rainbow or maybe a few different segments of Mr. Roger's Neighborhood.

No, it's not reading rainbow or mr. roger's, because I definitely remember those shows...

I think it was early to mid 90's though... possibly on TVO or PBS?

A main part that I remember is the train that went from inside the apartment/studio would bring drinks, or paint brushes and other things to the black man who painted on the balcony.
Also, this man was always in white overalls covered in paint.
The woman who had a computer and played the keyboard had all her equipment set up in the corner of the apartment up a few steps.

The Internet Movie Database (IMDb) (http://www.imdb.com/) is where I go to do this type of search. Try TV shows and the plot or story line. Hope this helps
