Don't use Gems for stuff that you can buy with Materials...save up the materials.

Also Special Offer Trains (using Gems) are better value than the normal offer trains - The LDE 2100 Triple costs 370 gems and has power 16. A recent Special Offer train costs 325 gems and buys power 50 ! Do the Math.
