For several years Railway Enthusiasts' Society ran trips from Newmarket via Glen Innes to Otahuhu and back, usually hauled by Glenbrook Vintage Railway's Ja 1250. The Broadway Limited is seen steaming through Penrose.
Railway Enthusiasts Society has operated rail excursions around NZ since 1958, some steam hauled using rolling stock from Glenbrook Vintage Railway which it established in 1970's near Auckland. See www.railfan.org.nz
