This set includes only the passenger car to a set that Lego sold over a decade ago. There is no engine, motor or track in this set, just the one passenger car. The fact that you could buy passenger cars separately was a nice feature. It is not clear that this strategy worked out business-wise, as Lego seems to have renounced individual car sets. But for this train, it meant you could build your train as you wished.As this set is long retired, prices are now well above what they were in 2003 and the set is largely going to be of interest to collectors.
