A set containing stations based on stations as found in the Netherlands

The Dutch Tram Set attempts to give an historical overview of Dutch
trams while ensuring quality gameplay. It works well with OpenTTD's
realistic road vehicle acceleration and for that purpose includes as
much actual vehicle properties as possible.

Vehicle capacity is optimized for gameplay (higher than actual seated
capacity, but lower than seated+standee capacity) and based on actual
vehicle length to maintain historic differences between vehicles. By
default, the vehicles can carry passengers only, but a parameter option
allows refitting to all cargo types.

Vehicles are drawn to their historic liveries. Some vehicles even come
in multiple liveries. A parameter option allows to change all liveries
to company colours (2CC), aimed at multiplayer games.

Vehicle prices are balanced against the default TTD buses. Tram purchase
is more expensive than bus purchase, but tram running costs are lower
than bus running costs to compensate for the higher initial investment
costs. Vehicles in the Dutch Tram Set are furthermore balanced between
themselves. Purchase costs depend on vehicle weight (material cost),
power (engine cost) and length (furniture cost). Running costs depend
on capacity (cleaning cost), speed (maintenance cost) and power
(electricity consumption).

A trainset that includes many Dutch engines and wagons. This set is available for TTDPatch and OpenTTD. Please read the manual, it's included for a reason ;).

This grf provides up to 4.256 (!) Dutch town names, large and small.
