New Hope & Ivyland is a railroad that is treated with a little bit of suspicion, or distrust, by those who have been around for a while in the railfanning community. Part of that is because they have stopped running steam as much as they used to, as I mentioned above. The #40 really only comes out mostly for fall foliage and Christmas and that's about it. But part of it also comes down to some other decisions that they made over the years that people haven't agreed with.
When they first took over the New Hope Branch from the Reading, they had a really nice little Canadian National 4-6-0, the #1533, which they bought in 1962. They ran that until around 1975, when it was taken out of service for an overhaul. In 1966, NH&I had acquired an ex-USATC/ex-Virginia Blue Ridge 0-6-0, the #9, and moved it to the property. They had been working on the #9 and had it near operation, and hoped to have the #1533 and the #9 both running for the US Bicentennial. The #1533 was found to need more work than could be accomplished in time and it was parked and never restored. Eventually the #40 became primary power, and they had issues with the #40's tapered-seat boiler washout plugs perpetually leaking, so the decision was made to cut the threaded Huron washout plugs out of the boiler of the #1533 with an oxyacetylene torch and then weld them into the #40. It's sat out behind the NH&I shops since 1975, and had parts borrowed from the spring rigging and the running gear and the backhead, and it's now a pretty rough-looking engine, with trees growing off the running boards. According to someone at SMS Rail Lines, when they approached NH&I about buying a steam locomotive, they wanted the #1533 but were stone-walled with the ol' "It means to much to us to sell" line and were rebuffed. SMS instead ended up with the 0-6-0 #9, also dormant for decades, and has been restoring that. The "means to much to sell but not enough to do something with it" mentality isn't just beholden to car guys.
NH&I #7 is a real sore spot with some, although not necessarily the fault of NH&I. When the Virginia Blue Ridge dieselized in 1963, they had two of the ex-USATC 0-6-0s, the #7 and the #9 still on the property. Steam Trains Inc., the operators of the NH&I in the early days, bought the #9, while a private individual who was part of Steam Trains Inc. bought the #7 for himself. The #7 and the #9 were moved up to the NH&I in 1966. The owner of the #7 was eventually forced out of Steam Trains Inc., for reasons I can't find, and it sat on a spur on the NH&I, while the #9 was being worked on to restore to operation. In 1970, #7 was sold to yet another private individual, who, like the person before him, did not have a good relationship with the NH&I management, and as the 1970s progressed, the locomotive could be found sitting derelict on a remote siding in the woods between Lahaska and Buckingham Valley, PA. In June 1976, the owner of #7 directed his attorney to sell the locomotive to the Menair-Fetzer Company with the provision that #7 had to be scrapped and not resold as a “complete locomotive” that could be restored. A private agreement was made between the Frank Menair and Jimmy McHugh (who was president of the NH&I at the time and owner of McHugh Company) for #7's driving wheels, complete running gear, driving boxes, throttle, air compressor and reversing gear. The McHugh Company then supplied a crane for the disassembly of #7. The parts to be saved were weighed and then scrap iron of the same weight was loaded into two Conrail gondolas along with the remains of #7 to make up the gross scrap weight needed. Most of the rescued parts were used on #9 when it was rebuilt in 1976. The sole reason for #7's unfortunate scrapping was because the private owner could not afford to make the necessary repairs to the locomotive to have it moved off the NH&I and he also did not want the NH&I (or anyone else for that matter) to have it as an operating locomotive.
The #9, after it's return to service in 1976 using the parts of the scrapped #7, ran about 5 years and then was parked in 1981. Again, like the #1533, it was parked out in the elements partially dismantled and sat there for almost three decades. It took numerous attempts by SMS Rail Services, after being rebuffed in their attempts to purchase the #1533, to get the NH&I to sell them the #9 and its been undergoing an exhaustive overhaul since 2008 and is getting near being ready to run again.
There was also a pretty decent-looking GE C30-7 that was running as late as 2017 that they cut up without any warning or offer for preservation a few years ago. The GE C30-7 isn't as loved by railfans as say, an EMD F7 or a GP30, but they were once a pretty common unit and are now practically endangered with very few preserved (and I don't think any of the preserved ones are operational).
