I notice when I put together a long consist there is some slack and elasticity in the rolling stock that leads to an oscillating effect. The locomotives in the front move at a constant speed but the rolling stock (especially at the end) sort of slinky back and forth. My rolling stock is mostly MTL with some AZL. Is there a fix for this or is it just part of the territory with z?

Gotta be in the couplers! Its that way in prototype railroads. Z scale, too...
Bolsters are where the side to side wobble comes from. David K Smith worked with this in Z and was quite successful.

I've heard sometimes a small spring on a couple axles, depending on the length of your train, sometimes causes a slight drag and reduces the "slinky" effect without bogging down the locos.
Usually the effect is found more with Micro-Trains couplers, AZL's are a little tighter so less effect.

The MTO couplers certainly can cause this affect. However there are underlying other issues that can cause this. One is trains going up and down grades (as if your layout has some, even small credit card height variations), turnouts/switches that cause some friction but more so about running at lower speeds that would allow all of the cars to almost maintain constant speed, rather than when running at a higher speed eventually the drag starts to stretch out to a more constant length.
As mentioned was to put the springs that MTL sold onto one (or both) point of the axle and then sticking it into the normal axle hole to create drag. You also can put the heavier cars in the back and the lighter cars so that it creates more drag (from weight)on the trucks axles to slow the back of the train down

From my own experience, this tendency is more prevalent with the knuckle couplers than with Marklin’s fish hook couplers. It doesn’t take a very long consist for this to show up. It gets magnified at curves and grades. Bad enough and you may even decouple. Some times just rearranging your consist can make a difference.
