Modellstrassenbahn Hamburg (Modeltram Hamburg)
The Modellstrassenbahn Hamburg (formerly "Arbeitsgemeinschaft OePNV im Modell Hamburg") is a corporation of several modelists of Hamburg urban traffic. The first time we met was 1989 to expose diverted models at Hamburgische Elektrizitäts Werke (HEW, hamburg electrical provider) consumercentre. Those were mainly Buses of Hamburg Transportation Community (HVV), but a few elevated and streetcars were exposed also.
1993 was an exposition on Hamburg fairground called "Hamburger Modellbautage". The organizer, Hamburger Messe- und Congress-GmbH, offered a free exhibition surface to associations and institutions with showcases and electricity installation. After two-month planning in September for fair initialization far over 500 exhibits from the area Hamburg suburban traffic were issued, mostly buses. Road and underground models in addition, were shown, mainly in the usual H0-gauge. There were i. e. tramyard Gaertnerstraße in the status of the turn of the century (gauge 1:87), some large-scale models and the even finished restored original Mercedes citybus type O 321 H from Hamburger Omnibusverein e.V., which was placed at the edge of the 100 square meters surface.
The exhibition Hamburger Modellbautage, which takes place in the two-yearly rhythm, became the most central meeting for the working group. Besides that exhibition the models are ordered by Hamburg traffic network, primarily Hamburger Hochbahn A.G. for exhibition purpose.

In 1997 was demonstrated for the first time after two-year lead time the streetcar segment system on a scale, built by several model construction amateurs, 1:87 (H0). The segments of this system are, apart from few exceptions, combinable freely together, so that new combination options result again and again. The vehicles, as far as it concerns Hamburg models, exclusively developed in the small series self's building. Vehicles of all epochs, begun with the first tramway cars from before the turn of the century to the motor coaches, which last run on the last line in Hamburg up to 1978. There were epochale allocations among the model construction amateurs of the group. While one copies only vehicles of the turn of the century, again only vehicles from the 50ies, and again with others the cars from the end time, completely rotten.
To all vehicles it is common that superstructures and chassis consist of corroded brass sheets and resinmolds. Motorizing exclusively occurs with electric motors (from Burmester) with a small rotor, which enables even fourwheel car with short axle base a outstanding handling. The drive is electrically upstreamed a digital decoder. The decoder is provided with an address consisting of four digits, and can be addressed by one like a pocket calculator looking controller, in order to let the driving electricity to the motor in a preset strength while electricity is permanently lasting at the tracks. This technology makes it possible to drive several vehicles on the same electric circuit independently.

One of the central points of the system is the original copied tramyard Ohlsdorf, from which in the original only today in a housing development present wartehaeuschen was preserved. Here is also one of the five final loops of the system. Besides that is attached the tramyard Gaertnerstrasse mentioned in the text above. Otherwise the modules are built after own conceptions, and only some configuration sections such as advertising pillars, waitingsheds, trafficsigns etc. are lent from Hamburg streetscapes, because the emphasis of modelling is situated on the vehicles. Beside vehicles from Hamburg operate also Cologners and Aachener vehicles on the system; permitted is what pleases. Each restriction regarding the vehicles would make the multicolored picture of the different types of play among the vehicles poorer. Finally operate also Hamburg vehicles of different epochs together, which never met each other in life.
The used track material is of the manufacturer Hartel, and was particularly developed for the reproduction of streetcars. The program covers even and curved track sections with appropriate spacer pieces for the double-railed building of tracks, as well as switches and crossings. With a fine saw these track sections were adapted for more complicated trackplans. The switches of the modules become electrically remote-operated, which takes place partially directly over a magnetic control in the vehicles.
The housings at the roadside is developed mainly from commercial housing-kits, which became modified partially, i.e. colour changed, supplemented or completely again combined.

The trolley consists of traverses, which is stuck partially at housewalls and otherwise to piles, as well as a trolleycable made of rubber, with which is considered to the mobility of the system.The individual segments of the system are standardized to be variously composed. The normal track-segments have a surface area of 70 cm x 100 cm, and the position of the tracks is the same at every segment to ensure the connection to every other segment too. On some segments an elevated is shown, whose electrification is shifted on a later point in time.
Most of the buildings are urban. Some of the modules are suburban. Some modules are shared to land development-technically peripheral quarters. Each module represents one epoch for itself. Some horse with carts and plaster of cobblestones reflect the 1900s . Others are that modern that one regains perhaps even the own car on the system segment.
Today there are about 50 trains with about 100 cars, mainly built after Hamburg streetcars. Up to 10 of them are on service at once, the other are at the tramyards.
