Have old (20+) year old locomotives, cars ,track and controller. Where can I find info as to how these will match up with current technology.
Is it possible to post photos on this forum?
Welcome.
You can post photos using a photo hosting site. There are some free ones.
I use to use photo bucket but they started charging so I dumped them a few years ago.
Others will have suggestions.

Are there other forums where a guy COULD get some help??
You are going to have to post some photos somewhere in order for people to be able to help you.
Yes, there are other forums, lots of them.
But, many of them require a new member to make a certain number of posts to get the "rights" to do things like post pictures.
If you think you have Bachmann products, then this is a good place to ask for identification.
But, if you think you have products from other manufacturers, then a more general forum is probably better. Some forums are specific to particular model scales, others are more general. Make sure you pick one that deals with the scale of the equipment that you want identified.
All forums will require a photo hosting site for photos.
At least you seem to be in N scale.

Mark has pictures of most locomotives and a lot of rolling stock. So, if you know roughly what type of car or loco you have, you may be able to find a match there.
As for your controller, it probably has markings on it that would tell us the manufacturer and model number, so posting that would help us help you.
It will also be important for you to understand if your trains have old-style "Rapido" couplers or newer style knuckle couplers, because the two types won't interconnect. Look here for info on couplers: https://www.nscaledivision.com/information_on_couplers.htm
Couplers can be changed on most cars from one type to another. Also, a transition car can be made with one type on one end and the other type on the other end, so that cars with both types of couplers can be run in the same train, if you end up with a mix of equipment.
