Ranked by relevance and common usage.
Keep "subways" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "subways" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "subways", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "subways" or choose a simpler alternative from the closest-match group.

Greg and I, both Filipinos, talk at the Lulu Island café this morning of the 20th of August of 2022. I tell him of my visit to the dried mango factory estate owned by my friend's relatives in Cebu, Philippines. There was a big house near the expanses of the dried mango factory. There was a games house. The auntie looked like an affable Chinese Hispanic. My friends and I ate mangoes every day. I tell Greg of my stay in Japan, where I frequently took the trains and subways. He mentions "bullet trains." I tell him that the PRC now has bullet trains. I tell him of Spanish-looking classmates with very long full names in my private school of La Salle Green Hills in Metro Manila. My classmate Julio lived in a big Spanish-style mansion with a garden driveway through the middle front. That look inspired my childhood dream that I told my mother about a "big house on a lot with a highway in the middle on an island." Oh, maybe, it was from James Bond.
