New York MTA-based Transit Groups

With heavy inspiration from New York City in Roblox developers and it being one of the largest cities in North America and the world, there is no shortage of real life and fictional MTA New York City Transit-based groups in the Ro-Transit industry. These groups have replicated almost everything transit-related since the early 2010s, from bus divisions to subway operations. Most of them have fictional names but some follow prototype operations. The option of trained or free drive will depend on the group solely.

Bus (NYCT Bus/MTA Bus)
Starting with littlechris4321, MTA took hold as a large group which spurred the interest of many operators. Due to the fact that MTA had become popular, it spurred many fictional operators and real-life based ones. These generally share the same models and have begun to explode in popularity with the advent of chassis systems such as WAVE and the A-Chassis. More recent systems have also used leaked buses to set up and eventually began creating their own models.

Some of these systems also use models never introduced by the MTA in real life, such as CNG NovaBUS LFSes and the like. Some groups have also rooted themselves in systems around fictional cities based on New York, such as Eastern Pacific Transit Authority's The Hamptons and NTA's Nassau City (based on Queens and parts of Long Island).

Bus models used are generally prototypical (to NYMTA specifications). Newer buses, particularly 2017 models and and up may have decals for Wi-Fi and USB charging capability.

Subway
Subway operations are well-known among the community, with a mix of both free drive and trained drive groups, simulating both real life and fictional maps. The lines represented are often in corridors (e.g. numbered lines and lettered lines would run separately). Again, these emerged from littlechris4321's operations.

Trains used in these maps are generally prototypical models.
