目前苏联铁路上采用两种型式的車輸,即d=950毫米(采用在大型貨車上和輕型結构客車上)和d=1,050毫米(采用在二軸貨車和1960年以前制造的客車上)。到1962年直徑为950毫米的車輪已占85％。今后随着新型車辆不断投入运用和旧型車辆的陆续报廢,直徑为950毫米的車輪百分比将不断增加并将接近于100％。 At present, two types of car transports are used on the Soviet railway, namely d = 950 mm (for large trucks and light structural buses) and d = 1,050 mm (for two-axle trucks and passenger cars manufactured before 1960). By 1962, 950 mm diameter wheels accounted for 85%. In the future, as new vehicles continue to be put into operation and old vehicles are gradually scrapped, the percentage of wheels with a diameter of 950 mm will continue to increase and will approach 100%.
