A loaded Maudslay Van Cool takes froever to get back up to full speed after climbing a hill. The Piece Goods variant is back to speed a lot faster.

That is rather curious, since the power and tractive effort values are the same for both. However, I will increase the tractive effort values for the next version and we shall see whether that helps.
