Streamlining of train sides and underfloor areas |
 |
evaluated |
 |
|
|
| A great part of the air resistance is due to surface friction along the train sides and roofs, and to the air drag of the underfloor equipment. There is some potential for improvement by streamlining the outer shell, optimising coach transition areas and underskirting.
