Nonnulla genera hamaxarum ex parte prima saeculi 20, cum notatione Whyte sua.
Notatio Whyte ex anno 1906. Ex libello pro opificibus ferriviarum anno 1906 publicata.[1]

Notatio Whyte ad hamaxam vaporariam ordine rotarum describendam a Friderico Methvan Whyte excogitata est[2] et parte prima saeculi 20 in usu esse ob opinionem in ephemeride American Engineer and Railroad Journal mense Decembris 1900 publicatam incepit. Systema Whyte numerum rotarum praecedentarum, tum numerum rotarum pellandi, tum numerum rotarum sequentarum enumerat, qui numeri sunt abs hyphen separati.[3] Alia systemata describendi, ut Descriptio UIC vel systemata Gallica, Turcica, Helvetica, axes pro rotas enumerant.

Ita hamaxa cum duabus axibus praecedentis (quattuor rotis), tribus axibus pellandi (sex rotis), et una axe sequenta (duabus rotis) est descripta ut 4-6-2.

Modus[recensere | fontem recensere]

Hamaxae cum articulis[recensere | fontem recensere]

Hamaxae cum articulis, ut hamaxae Garratt, quae reapse sunt duae hamaxae a fervefactorio coniugatae, symbolum + inter descriptionas quaeque hamaxae habent. Ita hamaxa Garratt generis "double Pacific" (Latine "Pacifica bina" dicere possumus) est 4-6-2+2-6-4.

Genera simpliciores ut hamaxae Mallet, quae axes non pellandi inter axes pellandi non habent, plures greges numerorum in medio habent. Ita hamaxa Union Pacific Big Boy est 4-8-8-4; sunt duas axes praecedentas, una grex quattuor axium pellandi, alia grex quattuor axium pellandi, tum duas axes sequentas.

Postpositiones[recensere | fontem recensere]

Postpositio T hamaxam cum lacu significat quia littera T est pro verbo Anglico tank (lacus); sine littera T currus materiae propulsoriae significatur. In usu Britannico, aliquando postpositiones hamaxae cum lacu significandae sunt plures: littera T lacum lateralem significat, PT est lacus in soraco, ST est lacus in ephippio, WT est lacus in puteo. T+T hamaxum cum lacu et curru significat.

In Europa, postpositio R hamaxam pro ferrivia dentata significet (e.g. 0-6-0RT) aut hamaxum quae directionem invertere potest (e.g. 0-6-0TR), quae est hamaxae Bi-cabine in usu in Gallia.

Postpositio F hamaxam sine flamma significat (e.g. 0-4-0F). Nota quod haec hamaxa currum materiae propulsoriae non habet.

Aliis temporibus sunt aliae postpositiones, ut ng pro hamaxis in ferriviis angustis (i.e. minus quam 1 435 mm) aut CA vel ca pro hamaxis quae aëri compresso utentur.

Hamaxae Diselianae benziniorumque[recensere | fontem recensere]

In Britannia, hamaxae parvae Diselianae benziniorumque maxime sunt in eodem modo descriptae, e.g. 0-4-0, 0-6-0, 0-8-0. Postpositiones possunt D (Diseliana) aut P (benzinii) et alia littera pro genere transmissionis: E (electrica), H (hydraulica), M (mechanica). Ita 0-6-0DE hamaxam Diselianam cum sex rotis et transmissione electrica significat. Si axes sunt vinculis scapisve (pro radio laterale) coniunctae aut singulariter pellatae, symbolis 4w, 6w, 8w utentur. Ita 4wPE hamaxam benzinii cum quattuor rotis et transmissione electrica significat. Descriptioni UIC pro hamaxis Diselianis magnis utentur.

Circumscriptiones[recensere | fontem recensere]

Cirumscriptio principia systematis Whyte erat habere nullam facultatem ad hamaxas insolitas describendas ut hamaxam Shay quae rotis a rotis dentatis (pro directe) pellandis utitur. Hoc res ad alia genera descriptionis adduxit. In Europa (extra Regnum Britanniarum) descriptio princeps est UIC, quae descriptio hamaxam exacte describeat.

Nominatio[recensere | fontem recensere]

In usu CFA (et minore ex parte in usu Britannico), pleraeque ordines rotarum nominatae sunt, saepe ex nomine hamaxae primae illae generis.

Ordines rotarum solitae[recensere | fontem recensere]

Ecce tabula ordinum rotarum solitarum. In pictura, frons hamaxae est sinistrá.
