You get less track with the Santa express, this set from Lidl also includes 2 short straights.
Not really a deal if you ignore the RRP, you can usually get these hornby starter sets for around £30-£40 so £50 is very steep. considering its high season you can get the Santa express for the same price and you actually get more track so cold from me. Argos
No, a bit big for that. Save £50 and use a piece of scrap paper.
