Subject: [PATCH] Fix: some articulated engines were picking up incorrect
 company colour for trailing parts following
 aebd97a15df3d30004f062ed97ce18d3dcc6d2b7; set trailing unit action 0 power to
 1 hp for engines, this violates the spec which requires trailing unit power
 to be 0, but fixes the issue; see also
