Ko te kāwai pūtēa diesel he whakahaere āhuatanga tōnua e hangaia hei whakamahinga mo te tuku ā-wāhi o te rūa me te pai o te tuku i te rūa diesel ki runga i ngā pūmau kē. Nā te hanga me te whakapai i ngā rauropi whakahirahira, pūtahi rānei ko te aluminium rānei ko te tokiwha mā, ka hanga ngā waka nei me ngā huatau e āhei ana ki te hokohoko i ngā momo rahi o te rūa, ahakoa te whakarite pai o te taumata rahi me te haumanutanga i te wā o te tuku.
