美濃町線の800形は車体中央を低床化した車両で、880形とは異なる乗降しやすさを目指しました。870形は札幌市電から移った連接車で、新造の部分低床車とは成り立ちも車体構造も異なります。
Type 800 on the Minomachi Line had a low-floor central section, taking a different approach to accessibility from Type 880. Type 870 was an articulated tram transferred from Sapporo, with a different history and body structure from the newly built, partially low-floor cars.
