Logistellar Transports

Logistellar Transports is the biggest and best known interstellar cargo transportation company, but they far from dominate the market. Heavy competition from smaller companies outbids them frequently, but there are even other giant logistical companies that almost rival Logistellar in size. 
Logistellar's success can perhaps be attributed to their close cooperation with Nubian Interstellar, having perhaps the most reliable transports. 
Logistellar's transporters are enormous bulk transporters always crowding the hyperspace routes. 
They also have a few smaller crafts with incredibly advanced hyperdrive engines that travel between colony worlds to deliver prefabs, vehicles and other deliveries, usually picking up from near the hyperspace routes and dropping off further into space. 
Most other logistical companies have a slightly different business model, sticking to one field or certain regions of space - this largely makes them more successful on a small scale than Logistellar, but Logistellar's ability to service almost all aspects of the logistical transportation business makes them the most default option.
