What was this book?

Thanks to https://tedium.co/2018/04/05/genesis-storytime-cable-channel-history/ ( and separately, thanks to whoever told me about this mailing list, because I would not have found this article without it. Who are you?) I am reminded of the story I once saw on this channel in.. 94? Very shortly after we moved to Falls Church, at least. It was a story about a kid who, one day after school, is at home when the wall opens up and a trains lets a lot of people off and he doesn’t like having this train suddenly appear in his house, and he goes to try to find out why it’s there. In the course of his investigation, he finds the city planning office, and the all powerful computer, and the secret behind this computer.

I believe it to be have been originally published as a picture book, because how else would have ended up adapted on this channel?

Does this sound at all familiar to people? Anyone? Bueller?
