A red-bordered triangle warning that the road crosses a railway on the level, with or without gates.
Also known as: Railroad crossing sign, Train sign, Gate sign
The level crossing warning comes in two forms the Convention keeps deliberately distinct: a gate pictogram where barriers protect the crossing, and a steam locomotive where none do. The distinction matters because an unprotected crossing needs the driver to look.
Warns that the road crosses a railway or tramway at the same level a short distance ahead.

Takes two distinct pictograms: a gate or barrier where the crossing is protected, and a locomotive where it is not — a distinction the Convention preserves precisely because an unprotected crossing places the duty to look on the driver.

Is often supplemented by a saltire-shaped crossbuck placed at the crossing itself, which in several countries is the marking that carries legal force rather than the advance warning triangle.
Contexts: Road signage
An equilateral triangle standing on its base with a broad red border and a white interior, carrying either a black gate seen side-on or the silhouette of a steam locomotive.
The crossbuck at the crossing itself is a diagonal cross, the same form as the saltire.
