About every 10 years or so, the National Park Service has a major upgrade of their Content Management System, and www.nps.gov is completing their migration to the new format just in time for the Centennial and National Park Week, which begins on April 16, 2016. Steamtown's webs has similarly been migrated over. https://www.nps.gov/stea/index.htm
While the look of the website is a bit more "hep to the jive," the biggest difference is in the use of the https:// protocol, which makes it more secure than the http: protocol.
Right around the time of the migration, a request from nps.gov came to all the parks to stop adding new content, so they can vet out old dead links. Schedules from the 2000s and other ghost protocols that lingered in the system.
This request came right around the time of the 2016 excursion schedule being finalized and made public. Therefore, as the new look goes live, it has some old information. It will be replaced this week and next.

How is your website doing? Is it time for an upgrade? It's never the wrong time to look at what you are saying to your public, and finding a new, fresh way to say it.

I can not get the link to work here.

Hi
The new link did work for me , with no problems ,,Pat

One critique as an editor:

"Locomotive Shops Repairs" as a title sounds way too much, at first glance, like major repairs had to be made TO the loco shops, not to locos IN the shops.

I just get a blank page (tried both Chrome and Firefox) so perhaps they still have some kinks to work out.

Explorer works just fine for me. The site came up immediately.

As for keeping websites up-to-date, that is indeed very important. Stale information is probably worse than no information at all. I revamped the website that I maintain for the Trolley Museum of New York recently, http://tmny.org, giving it a new, unique look while also trimming away infrequently accessed information and optimizing graphics for slow devices.

Another critique as an editor (since I don't yet know how to send the right person there a PM).

"Become a Junior Rangers"?

I suppose as with anything else new and this complicated, more little teething problems will come up and we can help the NPS folks find and 'optimize' them...
at least that's the spirit I'm commenting in, and I think Sandy feels the same way...

I've tried google and explorer and all, I get is a blank page also.

I'm using firefox and it popped right up.

I've been reading about a bunch of websites in several places that are having issues such as this--visible in one browser but not another, and/or people supposedly not being able to edit their (now rather old) sites full of data, such as a site listing historic places in a state.

Perhaps not coincidentally, I was ordered this morning by one hosting company for a client of mine to upgrade two websites from PHP 5.4 architecture to 5.6 or 7.0 immediately, or 1) be vulnerable to attacks or obsolescence, and 2) pay an additional fee a month for not updating.

So how thorough were the NPS updates?

That PHP thing is annoying.

Also, I'm guessing the NPS site is now hosted using Adobe CQ (or whatever they're calling it these days). Who knows what's causing the pages not to load. There are a million things that could be going wrong (websites can be complicated beasts, like steam engines, but without the charm).

I'm starting to see some NPS pages show up while others are still blank. There could be a lag due to CDN - Content Delivery Network - wherein pages of site content are cached in network servers and they haven't caught up yet to bulk changes at the NPS host.

Everything works here at home on the iPad .

More annoying than this are the ones who have all the bells and whistles, but your browser is saying you have to update half a dozen applications to even see the thing.
