I will take the experience and strategy moving forward of the railroad industry's management along with fact-based understanding of railroad markets and finances as an argument "of being right" over an argument that there's a rabbit to be pulled out of the hat, if only. Of course the vast majority of traffic covers considerably more than the marginal cost of carrying it, but because railroading is so capital intensive, the crux is whether there are adequate returns vs. the cost of capital. I'll also take the 30 some-odd year experience of what's worked and what hasn't over the argument against railroad costing. No doubt there is capacity available for targeted business, but, keep in mind defining capacity takes much more than yard dwell or "current trends".
I'm surprised that an observer as informed as yourself sees there being one 'correct' path that all Class 1s have taken over the past, say, 3 decades. Whether it be PSR, the vision-less mix espoused by the likes of UP pre-PSR, or BNSF's more growth centric model, many different approaches have been taken to running railroads, even within companies. Take CN: for years, especially towards the end of Harrison's tenure, their traffic growth levels were low. Now, they're outperforming most of the rest of the industry -- partially on account of some exogenous factors, but in large part because they've chosen to prioritize growth. And yes, they are doing well with it.
For whatever it's worth, there's a large body of historical scholarship that points towards this issue of myopia in rail management. The observers in the 1970s tasked with revitalizing the industry pointed out the exact issue I'm discussing here: railroads focus too heavily on cost-effectiveness metrics, and cut themselves out of growth. See:

As for the cost of capital issue, the STB estimates that to be about 10%. More than half of all rail shipments are >180 on the RVC scale, and operating ratios are in the 50s-60s these days. I daresay there's pursuable traffic that will (more than) cover their marginal capital costs, if extant. The question of capital costs is of course similar to that which asks whether or not railroads are at capacity. While there are of course massive nuances to the issue, the existence of a traffic decline and a fluidization of terminal areas generally produce latent capacity.

The past is very likely prologue when it comes to crew cost reduction and train size. All the while crew sizes have been incrementally reduced since the 1980's train sizes (and load factor) has increased unabated. The capital costs of infrastructure and locomotives, as well as the reduction in variable costs like fuel, has outweighed labor costs in the equation of fewer, bigger vs. more, smaller trains.
An anecdote for consideration for those who focus on big vs small trains comes from Conrail who was a first-in-class premium intermodal provider. One of their biggest intermodal trains also was one of their fastest, carrying sizable business with high service standards moving under contracted penalty and reward provisions. Even though service was provided on one of its biggest intermodal trains, they were very successful in reliably providing one of their fastest services.
You may be right, but as you yourself said, past trends are not necessarily predictive. Given the supply chain forces pushing people towards minimum inventory, and given the very real costs and safety risks incurred in running longer trains, this may well change.
The CR example, BTW, isn't a perfect one. A long train back then would be a medium or short train for today's railroads.
