The story

Ferro Transit Authority

The brief

Ferro Line connects eleven neighbourhoods that had never shared a transit identity. Riders speak more than thirty languages.

Our approach

We reduced every message to an arrow, a number and a colour. Floor markers, platform totems and on-board screens share one icon set drawn on a strict grid. Typography was tested in rain, at night and at speed.

The outcome

Journey times to transfer points fell in the first quarter after launch, and the arrow has become the line's unofficial logo.

If a sign needs explaining, it has already failed.
