There's a fairly new apartment complex that was built right next to the Lansdale regional rail station. I'm not sure if the cost/amenities match what you want, but that area is reasonably walkable and you should be able to take the bus up and down Main Street to get to grocery and other shops. They're actually doing a lot to revitalize downtown Lansdale and there are now some really thriving businesses on Main/Broad Streets.

If you're looking to move farther away, I recommend checking out the Regional Rail route and find places along that. Doylestown is another great area to live in that's walkable and has a good downtown. It's only about 30 min by car so it may be similar by train.
