Converting and rebuilding NSB Di5, Märklin 3148, to digital and high performance motor, including Telex

Updated  23.06.2012

NSB Di5
NSB (Norwegian State Railway) bought 17 second hand DB 260 and 261 diesel shunters in 1985 and 1987, to replace the Di2.  Di5 were built in 1956 to 1960 by MaK, Henschel, Deutz, Esslingen and Krupp. Already approx. 30 years old, they got a rather short time in service for NSB.  The last one was dismantled in 1998.
The locomotives bought in 1985 got numbers 5 861 to 5 867, while the 1987 ones became 5 868 to 5 877.  Number 5 868 was used for spare parts.  It was never in regular traffic.
