The #3 is now at the Otaru Transportation Museum in Hokkaido; a very historical point for Japanese railroads similar to Sacramento here in the US. Quite an impressive museum (the Porter provides their steam train rides around the grounds). There's also a much older Porter export (a Mogul also) which was the basis for an O.S. live steam model. Amazingly, an O.S. locomotive in 7-1/2" gauge goes for around $90k for 3-3/4" scale!
The Mission Creek 2-4-0 (I believe from George Roose's collection) is in service, however, at Western Village amusement park in Nikko (Westernmura) hauling an ex-Roaring Camp covered coach along with the former RC&BT #4 "Waipahu", an 1897 Baldwin 0-6-2T.
Researching those Japanese narrow-gauge steam operations was sure a fun job. Lots of them, too. Kyosan built several small 30" gauge saddle tankers for amusement park service into the 80s.
