History
The NS thought in the 70s of the twentieth century about to replace the Northern Side Lines. The famous Blue Angels Thanks to the Blue Angels are the Northern Side Lines, who was very unprofitable, to maintain closure. Because it was still not profitable enough, the question again whether there could take place. Cheaper and simpler operation came However, this other equipment needed.

To investigate how could be the unprofitable branch lines trains are operated with a working group was established in 1976, the Working Group Operating Neve Lines (WEN). The WEN is also known as WENN, because this working group was set up for the Northern Side Lines. Had to prove how the service implementation could be done in five Northern Side Lines. Cheaper from this study If mainline and connection between Leeuwarden and Groningen was the railway Groningen - Leeuwarden disregarded, but with later attention was paid because it was also to pick out here more profitability.

The main conclusions were maintaining frequencies, which were primarily hour shifts, and a good connection to the main railway Zwolle. One possibility was man operation during off-peak local and perform maintenance. It also looked at lifting the lines and execution to take place, or light rail on the line by bus. The findings of the working group were compiled in the report Project Operational Neve Lines (PEN) end of 1977

The conclusion that emerged was that the current service implementation was very expensive, and the light rail variant was not cheaper. A bus would be advantageous, but that would mean decrease of travelers, and eventually closure of the service. This was not the most ideal choice, making the group preferred to operate with a new-axle diesel equipment, which had to be. Performed the operation easier

A requirement here was that there had to be one-man operation, with the operator quiet hours the ticket could take the card vendor (or clerk at the station), who kept in busy hours. The sale of tickets easier, had the first class lapsed. This staff did not know, several tariff and selling tickets was much simpler. Staff had to be multifunctional, maintenance personnel had to be put. In the busy hours as a machinist Map Sellers in the off-peak provide care of the equipment, such as cleaning. The 40 operated stations, where you could buy a ticket through a clerk came largely replaced. Thirty stations went by without crew. The security should be improved and centralized, making it the spot Operated Relay Block System (TPRB) came in 1972. Here the operators could arrange the security sections themselves. Between Sauwerd and Red School was there from 1967 CRVL, either Central Radio Dispatcher, which caused a major train crash in 1980. Came the Simplified Central Traffic between Groningen and Sauwerd and Sauwerd and Delfzijl. Through all these changes could be from 320 to 250 people there. Workforce downsized This would result in a large cost savings, because at that time 59% of the cost of personnel existed. The planned one-man operation time is not yet introduced, but at a later time.

Equipment Selection

To implement the new tenure had new material coming. An important requirement was that had to be the existing design, in order to save. Draft realization and maintenance equipment derived There was also a high acceleration present to ticket sales by the lost time to catch up. During longer stops are at a station

On February 4, 1978 in Zwolle was the first railcar 627 008 of the German Federal Railroad to. This carriage was bet made on the Dutch rail network, for two weeks and especially the Northern Side Lines, because it was likely that this material was there to ride. This truck also went to the workshop Zwolle and Haarlem, to maintenance staff there to show the equipment and drove a few turns Utrecht - Geldermalsen. 17 February moved it back to Germany, and there was not yet decided ..

Besides these railcars 627 series and 628 series two-piece train was two alternatives are offered in the PEN report, namely trains Ym type of car builder Uerdingen and VT2E of Linke Hofmann Busch. The Ym was not chosen because there was a very low power and outdated design from the 60s. In order to place more powerful motors in terms of cost was impossible. The VT2E had a very low capacity, and the price was very high. This was chosen purchasing nineteen power cars and 26 carriages were put, derived from the German 627/628 series. This material was named DH1 and DH2.

Equipment Description
The Wadlopers were built between 1981 and 1983 by car builder Uerdingen AG for the Northern Neve Lines in Groningen and Friesland. The Wadloper Series consists of 19 motor (DH1) and 31 trains (DH2).

The trains that were ordered were some deviations from the German design. The air-cooled engine was a water-cooled, leaving space was saved. The bogies were replaced by a different type, the engine was a truck engine of the Cummins, and was planned in order to replace it. After 15 years These motors, however, are never replaced. The rail and liquid brakes were not built, and there was less electronics in the train. Maintenance would thus fall sharply in price.

The new trains were given an angular shape, and quickly got the nickname SRV car. The chairs came from the French company Compin and were also present in the then new City Regional Material (SGM). There were no partitions placed in trains, you gave a very spacious impression. The walls between the compartment and balcony were provided with images of regional landscapes.

The cab driver was very spacious, and had a glass wall to the rear window and speak with a pay table for the planned one-man operation. Folding mirrors were also placed next to the cabin, so there was list on the doors as they were closed. The conductor was not present at man operation.

The trains were DH1/DH2 the NS style, yellow. The doors dark gray, light blue and lower front shock stripes.

Because the name SRV car you did not give a thought directly to the Public Transportation, there was a competition for a new name for the material. The residents of the Northern provinces were allowed to choose, and in October 1983 was named Wadloper chosen from 48,000 votes. Set 3231 was the first to name the train.

Modernization
In 1995 it was decided to modernize what was already 14 years old. Equipment The old red benches were replaced by new substances seats in Coach lineup. Also, a "Stand-square" created. There was also a sweeper down the train and engine set placed in the gray color.

The 3101 and 3102 are set first in Tilburg overhauled, with subsequent DH1 other motor vehicles. Came the DH2-set between February and June 1997 turn. Then began the second technical review, which reducing measures were applied, and ATB-NG built. When the enable maintenance were temporarily Plan You came between Groningen and Nieuweschans, and other Wadlopers were deployed on other routes, not to use with different materials to create.

Joint efforts with DM 90 (Buffalo)
To replace the Blue Angels and Plan You were ordered trains DM'90 type. One of the requirement was to pair with Wadlopers. This was not planned, but has regularly taken place. To make this possible was DM'90 the maximum speed to 100 km / h beperktt because DH material could not be faster.

Bet
The trains were phased into service, whereby they took over a line in one of the Blue Angels. If this happened on the first line Groningen - Delfzijl on November 22, 1981. Groningen - Leeuwarden followed on March 7, 1982, in July Groningen - Red School. New Schans, and later also Leeuwarden - - Harlingen and Leeuwarden - Stavoren. A two months later the same happened with Groningen

There were problems with electronic contact between train and track, so there was a bad detection, and some trains of a trajectory seems to have disappeared, and crossing trees suddenly opened, as the train was not 'crossed'. This material was taken out of service in November 1982. Then there was revealed a mixed deployment with older equipment the problem was limited, Wadlopers came from March 24, 1983 back in service. From the timetable 1983/1984 came the trains also between Leeuwarden and Stavoren and Leeuwarden and Harlingen to drive.

Spits Train Leeuwarden - Heerenveen
In the 80s and 90s were Wadlopers only deployed in six Neve Lines. In the 90s there was also temporarily deployed in the Wadlopers Spits 18164 Train between Leeuwarden and Heerenveen. Because there were too many detection problems, and the Dog Heads reason that there were replaced by Leaders, to January 1, 1994 was a loose 6400 D-loc for posted from January 25, 1992. From 1994 Wadlopers were still only run on routes where axle counters were making the commitment Leeuwarden Heerenveen ended.

Zwolle - Kampen
Noordned is from May 30, 1999 transport taken on lines where the Wadlopers reason, and it required fewer trains because there was even more limited ridden. For this reason came three motor cars, 3101.3102 and 3103 and two 4 car set 3207 t / m 3210 released, while the NS two motor cars, 3101 and 3102, were committed to the Kamper Lijntje. Here were Axles Counters present, also also ATB-NG. When Noordned tight with equipment got stuck, went the two car set in the summer of 2000 to return to their original bet area. From then on it was gradually DM'90 deployed. When there are more DM'90 came to Zwolle, went railcars come to be in Zwolle, Arnhem and Groningen and later still.

Veen Express
The 3101 and 3102 went to Connexxion that transport kept between Almelo and Mariënberg. The 3103 was in February 2003 back to Noordned. Staff Connexxion was trained from 1 September 2002 to drive. With this material From 7 October, to drive motor vehicles and there were different colorways, namely green doors and advertising links.

Because there Wadloper the name was not found, very applicable in the Twente region was a competition. Here the name Veen Express emerged, which was then applied to the trains. The deployment lasted until May 26, 2007, when the draw for replacement of equipment Syntus, type RIBBON.

Arriva in 2006
In 2006, most Wadlopers leased by Arriva to bet on the Northern Side Lines in the next train series:
30000 Stoptrein Leeuwarden - Sneek - Stavoren
30100 Stoptrein Leeuwarden - Harlingen Haven
30200 Stoptrein Leeuwarden - Groningen, mixed with Buffalo
30400 Stoptrein Groningen - Nieuweschans to 5 November 2006. After that mixed with the Spurt (GTW).
30500 Stoptrein Groningen - Roodeschool
30600 Stoptrein Groningen - Delfzijl

The concession of the entire Arriva Noordned daughter went on the Northern railway on November 10, 2005, but was awarded to the parent company Arriva. One of the concession conditions were purchasing new equipment, with more comfort and faster acceleration. Arriva has developed D-GTW (Spurt) purchased. This soon came to an end the use of the Wadlopers.

Maaslijn
Veolia took at December 10, 2006 transport on Maaslijn (Nijmegen - Venlo - Roermond) on, and was looking for temporary equipment in anticipation of new trains, type D-GTW (Velios nicknamed).

Veolia had DM'90 hoping to be able to rent, but this was not because of a lease term of 10 years. This period was too long, as it would be. The new trains delivered much earlier The old Wadlopers this deadline is not gold and were also suitable for the line held by ATB-NG.

In April 2007 Veolia had the following trains:
3202, 3103, 3105-3108, 3110, 3111, 3114, 3117-3119, 3207, 3208, 3210, 3218, 3219, 3222-3228 and 3230

Because the name Veolia Wadloper did not pass corpse, the name was coined Maashopper.

The Maas Hoppers were deployed there in the next train series:
32200 Stoptrein Nijmegen - Venlo - Roermond
32300 Stoptrein Nijmegen - Boxmeer / Venray

Because there were Wadlopers very slow, and many defects were, could be many journeys not performed. Because of this reason the striker trains 32300 series not. As more Wadlopers from Arriva area were delivered, and reduce the peak hour trains to Boxmeer, the timetable stable.

As of December 16, 2007 was driven back by the striker addition to Venray. Until February 28, 2008 provided the Wadloper this peak trains.

Veolia had by February 15, 2008 4 more trains for the Maaslijn: DH1 3106, 3107, 3108 and 3118, and set it (mixed) in the following services:
32200 Stoptrein Nijmegen - Venlo - Roermond (reserve).
32300 Stoptrein Nijmegen - Venray. (Spits Train)

On 28 February 2008, the commitment of the Wadlopers terminated at the Maaslijn.

Drain and sales
By a violent storm on January 18, 2007 Wadlopers 3107 and 3119 were heavily damaged. The 3119 was not restored, and picked for restoration of 3107. The 3119 has been to Tilburg Workshop in January 2008.

The Wadlopers that were fallen into disuse, were kept in reserve as a spare. Many trains were stored in the workshop Amersfoort and still on the Dijksgracht Amsterdam.

In October 2008, four trains that were sold to Poland, now Sigma Wagon. Already designated for sale Chances are that all trains sold to Sigma Wagon Poland. On 13 May 2009, the 3102 and 3206 first transported to Poland. Here's a major overhaul occurred, and a paint job.

Overview aside Asked Wadlopers
The Wadlopers from Arriva, Connexxion and Veolia are placed after the end of deployment in a shed in Amersfoort or the Dijksgracht in Amsterdam waiting for a buyer or demolition if no buyer reports. On 13 June 2007, 3204 and 3220 trains first made in Amersfoort. Aside
