I learned a new term today, thanks @1stSgt22 and nice one. VarietyErrors says that with a reeded edge, the reeds sometimes look like railroad ties, too. That's cool. https://varietyerrors.com/coin-price-guide/partial-collar-coins-price-guide/
The coin in the OP isn't a railroad rim. A railroad rim is also known as a partial collar. Here is the write up from error-ref. The edge pics are good, but they don't do a very good job of showing the slight spreading of the coin in the areas were the collar doesn't contain the planchet www.error-ref.com/partial-collar/
