Since you asked some quick questions, my top 10 are as follows:
1) Are there any remaining Gilbert tooling that they have not used yet that can still be revived? (i.e. The Franklin Set, Animated Passenger station)
2) Will they expand the Fastrak system to include trestles, Graded Crossing (even without the grates) and IR signals?
3) Will they consider reissuing Gilbert Accessories such as the Cattle loader this time with Sounds to make it more appealing? (Shown in earlier catalog but cancelled due to price and lack of orders)
4) Since they have the loading car, will they consider making the operating Milk car and platform?
5) Will they look at sales in all other scales and consider making what sells well in those for S? (For example a GS4 in Southern Pacific Daylight colors.)
6) Since Lionel is hesitating about modern freight, any chance they might survey us and give us a choice of 4 modern cars and ask us which one we would most be willing to buy to enhance their chance of a good sell out?
7) With so many Northern Pacific Passenger cars, any chance they would make a Legacy Alco powered A and Powered B set of engines so we can pull all the cars they issued? (Worded differently... Can we get a Legacy powered B unit please?)
8) Would Lionel consider making an engine in both Legacy and Lionel Chief formats at the same time as a Built to order? (This way those who invested and prefer Legacy can buy that version for more money and features and the Lionel Chief customers can buy the lower priced item they prefer)
9) Any chance of making a Thomas the Tank engine in "S" scale with sounds and smoke to help compete with Bachman and bring new people to Flyer?
10) Any chance of converting non scale specific O gauge operating accessories to work with "S" scale such as the Culvert loader?
