The NS1600/1800 is derived from the French BB7200 locos. They are designed for intercity trains, double-deckers (DDM-1) and good trains.
Before the 1600s were ordered, there were tests carried out with two trial locomotives. These were the SNCF BB7000 (the test model for the later BB7200), and the 1600P from the German Henschell company. The 1600P (DB202.002) was fitted with AC motors. Eventually, the BB7000 was chosen despite many small changes being requested by the NS. The first round saw 'only' 20 locomotives ordered from Alsthom. This order later grew to 48. Later still, another 10 locomotives were requested to run the DDM-1 train sets in push-pull mode. Eventually, all the 1600's were converted for this duty.
One noteworthy feature is that this was the first NS locomotive where the driver sat on the left. The first 1600 entered service in 1981.
On the 6th April 1982, the 1601 was named 'Amsterdam' and was painted with the city shield. Since then, all the locomotives have been named after cities, and now carry the appropriate shields. Here's a list of the various numbers and cities that are assigned to the locomotives:

Since privatisation in May 1999, NS-Reizigers, the passenger division, and NS-Cargo, the freight division, needed to divide up the rolling stock and locomotives. Because of this, locomotives numbered 1638 and higher became renumbered the 1800 series, so that the two could be told apart.
In honour of the transfer of locos 1601-1637 to NS-Cargo, 1637 was repainted into NS-Cargo red with the white NS/Cargo lettering, and delivered into service on 7th January 1999. It's the intention that each other class 1600 will get repainted into the red/white colours at it's next scheduled major service.
In May 2001, four of those 1600s were given back to NS-Reizigers (1634 to 1637), and hence were also renumbered to the 1800 series. 1637 then lost it's NS/Cargo lettering, but remained red.

The NS Class 1800 is available in 4 colour schemes as part of the same download:
