An interesting comparison of drive wheel diameter effect was on the PRR's Columbus-Sandusky line in 1956. There was a big coal traffic surge up to Sandusky and the Pennsy was short on operational power. They had tons of stuff in the dead lines but some of it had been parked since the Great Depression and couldn't be easily revived, the I1s 2-10-0s were beat to death, and the Q2s 4-4-6-4 Duplexes had all been kicked out of service with cracked boilers. So the Pennsy moved as many J1 2-10-4s they could spare and then leased a bunch of ATSF 5011-class 2-10-4s as well.

The big difference between the two engines was that the PRR J1s had 70" drivers (and there's a story regarding driver diameter there too) and the ATSF's 5011s had 74" drivers, the largest ever fitted to a 10-coupled engine. The consensus of the PRR crews was that while the J1s were worth a few more cars and were easier to start a train with, but the 5011s rode better at speed and could cover the Columbus-Sandusky run considerably. And of course the firemen preferred the oil-fired 5011s over the coal-fired J1s, but that's besides the point

Another that comes to mind is the Boston & Albany J-2 Hudsons. The B&A was a New York Central subsidiary, and had a much more sawtoothed profile than the rest of the NYC system, along with shorter hauls and a higher stop density with their passenger trains. Because they needed an engine that could handle hills better and accelerate away from stops faster, NYC took their J1 Hudson design, which had 79" drivers, and shortened them down to 75". Among other changes were the square sandbox with a higher capacity (for starting and climbing grades), and the short 4-axle tenders (no need for a high capacity tender with 200 mile runs, and it was less dead weight being towed around by the engine). The B&A was dieselized by the NYC fairly early on, since those diesels handled the grades even better, and the J-2s found themselves bumped into commuter service elsewhere in the NYC system, since those shorter drivers were nice for the frequent starts and stops of commuter service.

An easy way to get a little more speed out of an older engine design was to install thicker tires on the driver center to increase the effective wheel diameter. A visible example is on Frisco #1020, which was a 1910-built Pacific that Frisco dressed up for thee Firefly. They installed 2" thicker drivers to bump the diameter from 69" to 73", and then used a lot of sheetmetal to disguise that this was a 30 year old Pacific with a pencil-diameter boiler, tall shotgun stack, oddly large cab, and clunky Cole trailing truck. Note that the cars behind it are old clerestory roof cars that the Frisco disguised with balloon roofs and lower skirting to hide their age. This was a bucks-down effort, for sure.

Union Pacific's 4014 Big Boy is steaming through town again, on its way to Colorado. I didn't go this time.

Yeah, I'll probably never see that one live. It won't come this far east, and even if I wanted to go west to see it, I hear that the crowds and traffic are nightmarish. I think it was Rochelle, IL this year where traffic was backed up over 2 hours to get to see it.

Speaking of engines I won't be seeing live, I certainly wont be seeing Arcade & Attica #18 running this year. I've been hoping to get out there this fall, but the last fall trips with it are this weekend and I'm busy both days. They are running trains for the Christmas season, like any tourist line with a brain in their head, but oddly they are not using the #18 for those trips. Which is kind of backwards considering a lot of operations these days only fire up their steam locomotive at Christmas time (looking at you, New Hope & Ivyland)

This make me realize that in this country and only a very few others, passenger rail has achieved the status of horse ownership, but with less mess.

I was also kind of hoping that CPKC was going to use #2816 on their Holiday Train and maybe bring it down the old D&H to Mechanicville, but while they've announced the Holiday Train schedule and they are coming down the D&H, there's been no mention of the #2816 being used for it. So if they are using the #2816, they're playing it real close to the chest. Just seems kind of wild if they only use the #2816 for the merger ceremony train and then don't ever use it again.

They did use it on the "Holiday At Home" train back during the pandemic, where they moved it around the Calgary yard for a video, which was the first time the #2816 had run, or even been seen, since Hunter Harrison had taken over CP and ended the CP steam program.

Look at poor Canada, who is the only country in the G8 to have never had high speed rail in any way, shape, or form. They got close with the United Aircraft TurboTrain trainsets, which were capable of 160+mph operation and were certified to run 125mph on CN rails. Then on the maiden voyage, the trainset struck a truck at a grade crossing at 25mph and despite no onboard injuries and the train being able to continue it's run, Canada got all nervous about high speed running and restricted them to 95mph. If they'd been run at 125mph, they would have been as fast flying on the Toronto-Montreal run they were assigned to, able to do the run in about 3 and half hours. Instead the trip took about 4 and a half, which wan't nearly as advantageous, and then the UAC Turbo Trains were plagued with niggling reliability issues, and Canada has never looked into HSR again with any seriousness.

On the subject of the poor treatment of passenger service, the poor Amtrak Adirondack's ongoing saga has the D&H fan in me weeping. The NYC-Montreal train was parked during the pandemic, then took 3 years for it to be resumed. Immediately after service resumed in 2023, CN, who owns the 42 miles from Rouses Point to Montreal, slapped the line with a 10mph speed restriction due to a combination of the track being allowed to deteriorate during the pandemic and possibly heat kinks in the rail. That meant that the train took over 4 hours to go from Rouses Point to Montreal, and on June 26, Amtrak suspended service "until further notice" north of Albany over the track conditions and tore into CN over inconsistent application of the heat order policy. CN meanwhile alleged that Amtrak had failed to pay for maintenance to the track, which Amtrak disputed. Service was restored to Saratoga Springs by July 24th, 2023, and service back to Montreal resumed on September 11th, 2023.

There was then another pissing match this spring, when Amtrak first chose to cancel the train entirely, beginning May 19th , again due to CN's rules on track speeds being reduced to 10 mph under current track conditions any time ambient daytime temperatures exceeded 86 degrees Fahrenheit. Amtrak then chose to run the Adirondack only as far as Albany-Rensselaer, essentially making it another Empire Service until June 29th but soon extended the daily round trip to Saratoga Springs. Then the resumption date to and from Montreal was pushed back to September, with it not making a full trip until September 10th. The Adirondack has now missed two summers of full service due to Amtrak and CN being unable to come to an agreement on track work.

Now, on November 10th, as part of a constricted-capacity plan while East River tunnels are taken out of service for overhaul, the Adirondack is being combined with the New York-Toronto Maple Leaf between New York and Albany-Rensselaer, NY. Passengers on both trains will suffer. Northbound, the Adirondack’s current 8:35 a.m. departure from Penn Station will be pushed ahead to 7:15 a.m., when the Maple Leaf leaves. But the Adirondack’s departure from Albany remains at 11:40 a.m., stalling passengers at the station for 110 minutes instead of 27 during the change from a dual-mode locomotive to diesel power. The current schedule already has a lengthy delay built in at the Canada-US border to allow Canada Border Services Agency personnel to examine travel documents. This consumed 78 minutes on September 29th. Four U.S. Customs and Border Protection agents boarded the southbound train two days later at Rouses Point, NY; it departed on-time after 57 minutes. Southbound, Maple Leaf passengers will wait an extra 65 minutes for the Adirondack. The two trains’ lack of connectivity to Northeast Corridor service caused by early departure and late arrival at New York will be exacerbated.

I would honestly love to ride the Adirondack, at least as far as Rouses Point, but the train has been in such a constant state of flux that it seems like you have to catch it on the two weeks a year where it actually runs the full length.  Make you wish for the good old days when D&H ran it.

Also as part of that East River Tunnel reconstruction, Amtrak has announced the revival of the Floridian name, last seen 45 years ago. Amtrak is trying to reduce the number of services out of New York Penn Station due to reduced tunnel capacity, and so, with the near identical Silver Star and Silver Meteor both running out of New York to Miami, Amtrak made the decision to shelve the Silver Star. Instead, it will be merged with the Chicago-Washington DC Capitol Limited, resulting in a "direct" Chicago-Miami train that will use the old 1971-1979 Floridian name. It will head west from Chicago to DC on the Capitol Limited route and then swing south onto the Silver Star route for a shot down the coast to Miami. I use "direct" in quotes since that's a pretty big jog east, unlike the old Floridian (and it's South Wind predecssor) that ran diagonally down through Indiana, Kentucky and Georgia to Miami.

The original Floridian on Monon street-running trackage (now long gone) at Lafayette, Indiana behind the troublesome SDP40Fs.

Here is a weird bit of trivia I ran across (which might be obvious to you, but a bit confusing for others) that you can confirm or clarify Nick:

What is the difference between a train and a locomotive?

From what I understand it a "train" is effectively a service and is on a schedule.  So a locomotive, even if it is attached to multiple cars, if its not on a schedule, it's not a train.  You can even have two groups of engines and cars could be considered the same train because they are running the same schedule.

I loved watching it roll through there in the 90's. It just seemed so bizarre having never been exposed to street running anywhere else.
