here is a film made by BNM from the late 50s early 60s that might be of interest. there is a good chance that the last BNM train has not yet run. many of the currently still in situ railway lines are to be turned into greenways and it is from what i know lighty that they will use the railway in the construction of the greenway. unfortunatly the line will be lifted in the prosess
also you could visit the stradbally woodland railway and the cavan and letrim railway and ask about it. alot of the people there have an intrest in BNM stuff. also Sean Cane and ted mc avoy on facebook are also very knolageable in BNM
