I loaded a dozen episodes of “Jordan, Jesse, Go!” onto my music player and had a very pleasant morning riding the train through Perak listening to nonsense and enjoying the view. I took about a hundred photos out the train window, all of which are terrible.
Key landscape features include:

Home-made structures built from corrugated metal. Outside of Germany there’s nowhere in the world where a train ride won’t expose a few of these. Malaysia, though, is chock-full. I saw factories, chicken coops, turkey barns, homes, and restaurants, all with great-looking patchwork roofs.

Delicious weeds. Medians and wastelands are full of banana stands and little patches of sugarcane. Since these things seldom grow from seed I can’t imagine that they’re volunteers… perhaps there’s some sort of Jimmy Rogers-type conspiracy to make sure that there are always free snacks by the roadside.
Not pictured due to photographic limitations: Dinner-plate sized lotus flowers growing in swampy places, and Lots of Vintage Vespa Scooters rolling around way out in the country.
