'''Notasi Whyte '''adalah sistem klasifikasi [[lokomotif uap]], [[Lokomotif pembakaran dalam|beberapa pembakaran dalam]], dan [[Lokomotif listrik|listrik]] menurut susunan roda yang diciptakan oleh Frederick Methvan Whyte, dan mulai digunakan pada awal abad kedua puluh menyusul terbitnya editorial edisi Desember 1900 pada jurnal perkeretaapian ''American Engineer and Railroad Journal''. Notasi Whyte menghitung jumlah roda
Dalam notasi Whyte, lokomotif dengan dua gandar
==
===
Bentuk dasar dari notasi ini adalah angka-angka yang menunjukkan jumlah [[Roda depan|roda muka]], [[roda penggerak]], dan [[roda belakang]], yang dipisah menggunakan tanda hubung.<ref>{{cite web|author=Thompson, Keith|date=2006-05-01|title=Builder's plates: A locomotive's birth certificate|url=http://www.trains.com/trn/default.aspx?c=a&id=201|publisher=[[Kalmbach Publishing]]|archive-url=https://web.archive.org/web/20081122011919/http://www.trains.com/trn/default.aspx?c=a&id=201|archive-date=22 November 2008|access-date=2008-02-08|url-status=live}}</ref> Contohnya, lokomotif dengan dua gandar depan (empat roda), tiga gandar penggerak (enam roda), dan satu gandar belakang (dua roda), disimbolkan dengan {{whyte|4-6-2}}, dan dijuluki ''Pacific''.
=== Lokomotif gandeng ===
[[Lokomotif gandeng]] seperti [[lokomotif Garratt]], yang terdiri atas dua unit terpisah yang digabung menggunakan [[Pendidih|ketel pendidih]] biasa, menggunakan simbol plus (+) di antara susunan roda masing-masing unitnya. Dengan demikian lokomotif uap "Double Pacific" disimbolkan dengan notasi "{{Whyte|4-6-2+2-6-4}}". Untuk lokomotif Garratt tanda + digunakan meskipun tidak ada roda tengah tanpa penggerak, misalnya LMS Garratt {{Whyte|2-6-0+0-6-2}}. Hal ini karena dua unit mesin lebih dari sekadar bogie berpenggerak. Keduanya merupakan satu kesatuan yang membawa bahan bakar dan tangki air. Tanda + merupakan jembatan antarketel uap yang menghubungkan dua mesin.
Lokomotif uap jenis Mallet memiliki sambungan rangka di bawah ketel uap tempat tidak ada roda tanpa penggerak di antara jajaran roda berpenggerak. Biasanya, rangka muka dapat berayun, sedangkan bagian belakang rangka bawah menyatu dengan ketel. Jadi, susunan gandar [[Union Pacific Big Boy]] adalah {{Whyte|4-8-8-4}}; empat roda muka, dua set roda yang terdiri dari delapan roda penggerak, dan empat roda belakang.
=== Lokomotif dupleks ===
Untuk [[lokomotif dupleks]], yang mempunyai dua set roda penggerak yang dipasang secara kaku pada rangka yang sama, metode yang digunakan sama seperti untuk [[Lokomotif Mallet|lokomotif gandeng Mallet]] – jumlah roda muka diisi terlebih dahulu, diikuti oleh set roda penggerak muka, diikuti oleh set roda penggerak belakang, diikuti oleh roda belakang, setiap nomor dipisahkan oleh tanda hubung.

Beberapa akhiran tertentu dapat digunakan untuk menandai jenis lok tertentu, seperti [[lokomotif tangki]]:<ref name="irs">{{irs-el|el=17}}</ref>

=== Pembakaran dalam ===
Notasi ini dapat digunakan untuk [[lokomotif bensin]] maupun [[Lokomotif diesel|diesel]], dengan cara yang sama dengan lok uap, seperti 0-4-0, 0-6-0, 0-8-0. Apabila semua gandar lok disambung dengan batang penggerak atau rantai atau mempunyai penggerak sendiri-sendiri (alih-alih batang samping), digunakan notasi 4w (4 roda), 6w (6 roda), atau 8w (8 roda). Untuk lokomotif diesel besar, [[klasifikasi UIC]] lebih umum digunakan.
