As a new convert into Lego Trains, I see that unless I'm willing to spend a small fortune in buying the 9V straights, I have very little opportunity to extend the basic oval as supplied in the Cargo Set. Lego themselves are out of stock of the Straights/curves pack, the same goes for the points pack (not everyone wants to buy 1 x l/h and 1 x r/h in a pack. I know I don't) and as for the shops.....forget it, "not in stock"..."unable to determine next delivery"..etc, etc.
As a consumer, I believe that had I looked into this more thoroughly BEFORE buying the set, I would very likely have gone the OO route where track is available in multiple variants; crossovers, finescale, concrete / wooden sleepers, long / short points, etc. I don't want to run trains round and round (one sure-fire way of putting youngsters off buying trains is boredom, the big players in the OO producers quickly realised that, hence the "extras" they offer from the very beginning), but Lego is doing everything it can to disappoint the consumer.
I appreciate that AFOL's are the minority, but they are the ones with the funding, and for Lego to persist in their current way of marketing their products is a sure way to put people off buying their products. Just spend a couple of hours on internet auction sites and watch the prices of straights. The all-plastic variety is rarer than hens' teeth, and 9V track is being snapped-up by those that already have 9V gear. I have spent two nights checking the on-line auctions, prices are simply outrageous, and right now my brand new £129.00 (child's toy prices??) Lego Cargo set is looking more like being placed on an auction site than me keeping it. Disillusioned already.
