Since my son was given a lovely set of around 65 books, with stories of many of the Thomas the Tank Engine characters, one new character really grabbed him - Rocky. Perhaps egged on (ever so slightly) by me and my cries of 'Rocky, Rocky', he always wanted to hear his story. The natural next step was to add Rocky to the train set collection, and he absolutely loves it.
The crane comes in three parts with the longer middle piece housing the Crain mechanism itself. It's very sturdy and well made and, though it goes almost everywhere with us (in the car, to the shops etc), there has been no chips or marks and this is a real sign of quality.
The set fits well on the track and takes corners well. The only downside is that because of the crane, when my son (and I) make a bridge with the Brio track it doesn't fit underneath due to its height.
