Landship

Landships are large vehicles made of steel—and, on occasion, wood—used to transport freight and passengers long distances over land. Comprised of one or more "cars" linked together into a train, these vehicles travel along fixed rail tracks at speeds comparable to a horse at a brisk canter. Unlike a horse-drawn carriage, or the more modern automotive carriage, landships have the advantage of being able to travel much longer distances without any need for rest.
Powered by the same revolutionary technology as the modern automotive carriage, the Duality Engine, landships require little hard labor on the part of the crew. As landships travel only on set tracks, learning the basics of how to drive them is relatively easy.
The difficulties arise when considering the different circumstances that may arise while driving a landship. For instance, horse-drawn and automotive carriages come to a halt soon after the driver wishes to do so. The considerable mass and momentum behind a landship, on the other hand, means that drivers must begin braking well before a potential impact.
Another potential challenge are the rail tracks themselves. Landships rely on the tracks being relatively clear of debris in order to function correctly. Though not as much of a consideration in the Pāll-tanír where the vehicles are being tested in a pilot program, there is some concern that leaf litter on the tracks might cause unwanted slippage in the more vegetated areas of the world.
Any turns in the track have to be navigated carefully, as well. If a landship rounds a curve at too high of a speed, the driver runs the risk of derailing, which would be a catastrophic mistake. As such a driver must know when to vary the speed of the landship.
Despite all these potential difficulties, landships are nevertheless likely to form a part of the Dominion's core logistics infrastructure in the future. The benefits are simply greater than the drawbacks and institutional knowledge about best practices, and safety measures, among other things, will only improve with time.
