Here are some signs in Taimali (Tàimál? / ???), Taidong County, Taiwan. In all cases of distinctive spellings, they’re in Tongyong Pinyin, even though they should have been replaced by Hanyu Pinyin years ago. When the change to Tongyong Pinyin was implemented, however, signs under national control (e.g., highway signs) were switched relatively quickly throughout the country. This, however, has not been the case with the switch to Hanyu Pinyin, especially in the south.
Note that the “Taimali” in the sign for the Taimali Railway Station is on a sticker rather than on the original sign. This is a bit odd, given that this is spelled exactly the same in all of the romanization systems commonly seen in Taiwan: Hanyu Pinyin, Tongyong Pinyin, MPS2, and bastardized Wade-Giles. So maybe what’s under the sticker was just an error. Taiwan’s signs certainly have their share of typos too. (Sometimes the authorities will even use a sticker to “correct” the right spelling with something else.)
