Modular transit system

A modular seat assembly comprising:

• an elongate support spine extending longitudinally from a first end to a second end;
• a seat portion connected to a front side of the support spine, wherein each of the seat portion and the support spine includes one of a complementary pair of interlocking portions, and wherein the interlocking portion of the seat portion slides onto the interlocking portion of the support spine over the first end;
• an end cap lockably disposed over the first end, wherein the end cap prevents the seat portion from sliding off of the support spine;
• and
• a first strut secured to a back side of the upper portion and a second strut secured to a back side of the lower portion, wherein each of the first strut and the second strut extend longitudinally in a direction transverse to the support spine;
• wherein the end cap releasably locks onto the first end and may be unlocked and released therefrom in order to remove the seat portion from the support spine;
• wherein the interlocking portion of the support spine comprises a first elongate track extending longitudinally along the support spine from the first end, and the interlocking portion of the seat portion comprises a second elongate track that slidably interfits with the first elongate track;
• and
• wherein the central portion comprises a bend and the upper portion projects upwardly from the central portion and the lower portion projects horizontally from the central portion at an angle from the upper portion.
