Both NMRA and TCA are almost entirely volunteer organizations with relatively small budgets and modest numbers of members. If you want TCA (a toy train collectors organization, in the main) to do more of what NMRA (a scale model railroading organization) is doing, you're going to have to do it yourself, or find some TCA member who is interested in doing it. There is no budget for paying people to do such things in either NMRA or TCA. These are volunteer offerings of members, nothing more, nothing less. The reason TCA doesn't do scenery clinics, prototype clinics, etc. is that few members know or care about such things is my guess. That's why people belong to the NMRA and various historical societies. That's their strength. The NMRA and the historical societies don't toy train layout visits, demos, toy train history, collecting research, etc. That's what the TCA's strength is. Expecting the TCA to do such things is a bit like expecting the Aardvark Fancier's Society to have activities related to tree sloths
