This printout keeps the entry for Cold Metal Rail itself: its description, reference card, Connections, questions, evidence, related smells, record details, states, names and citation. It leaves out your own notes, the map, the lists of paths, routes, stories and fragrance directions, and the lists headed “Also linked to” (other entries that share its place or material) and “Linked from”; they are on the page online.

Cold Metal Rail
A cool metallic touch-and-smell experience associated with railings, transit and cold outdoor metal.
Its type is State because its name already describes a condition, such as wet, toasted or after rain. That is a way of grouping entries; it is different from the states listed for this entry, which record how a smell is met. See how smells are grouped.
Setting: material. An editorial word for the kind of place or occasion the smell belongs to, not a smell word.

QUESTIONS ABOUT COLD METAL RAIL
Cold Metal Rail, question by question
What does cold metal rail smell like? EDITORIAL
A cold metal rail gives a sharp, faintly metallic impression, more felt than smelled, with a clean, mineral tang close to keys or loose change. On a frosty day the air around it feels crisp and thin, and the whole impression is bright, brief and slightly hard, the opposite of the soft warmth of wood or fabric.
It is met on stair rails, station barriers and handrails in winter, and on playground bars, gates and bicycle frames. Many people notice it on cold mornings outdoors, when bare hands grip a railing on the way to a platform or up a flight of steps.
One VERIFIED scientific claim from one published source is recorded for this entry: The metallic smell of touched iron. This claim says only what its source supports, in the scope shown with it.
How do people describe it, and what is it compared with? EDITORIAL
Cold Metal Rail is a perceptual state profile and does not claim that metal has one intrinsic odor.
Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.
01WHAT THE EVIDENCE SAYSVERIFIED
What the evidence supports
This one VERIFIED scientific claim, from one source, covers how it is described or perceived and the chemistry reported. How the scientific evidence was produced: a broad account. This claim says only what its source supports, in the scope shown with it.
What is editorial
The description, smell words, associations and related smells on this page are written by SmellBook's editors and labelled EDITORIAL or CULTURAL; a claim below does not make them VERIFIED.
The authors report that the metallic smell noticed after touching iron tools or coins is a type of human body odour, linked to the breakdown of peroxides on the skin; rust, drinking water and blood containing ferrous ions cause a similar metallic odour.
Iron tools and coins handled by people; the source does not study railings or cold outdoor metal, so it applies to them only as touched iron, and the abstract names no single compound.
How this was found: Broad account. A broad statement about how an aroma forms, how it is studied or what a term means, rather than one measurement. Source: primary study.
Each step is a relationship SmellBook editors recorded in the knowledge graph, named as it is published there. Paths are not ranked or personalised, and they do not mean the smells smell alike.
CULTURAL: This entry's associations depend on context, language, memory or culture; its description and smell words are editorial. It says nothing about research or historical evidence; evidence for this entry is shown separately: VERIFIED.

outdoorsEDITORIALThe entry records a setting in this state. (“cold outdoor metal”)Indoor vs Outdoor
A state says how an entry is met, such as wet, aged or roasted. It does not create a new smell, and it adds no scientific fact by itself: states marked EDITORIAL come from the entry's own records, and only those marked VERIFIED are reported by a VERIFIED claim.
