Hi Ken,
Hi Ken,
Glad you liked the interview.
In HO scale in my 1952 era most cars were 40' long. There were some 50 footers and some shorter ones too so on average a car would be 40'. In HO 40' is just abouit 6". So a 30 car train is about 15' long without locos or caboose.
I typically put two 1st generation diesels or a cab forward on a 30 car train. So lets add about another 18" or so for motive power on the head end. And add another 5" for the caboose.
Which makes the longest trains about 17' long.
I deliberately made the loco consists a bit underpowered for such a train on my ruling grades. The ruling grades on both my old and current railroads come in at about 2.8%. To reliably get up the hill I run helpers. I prefer using a second crew for the helper unit (adds to the fun - well at least some folks think so). Because my trains generally don't need much help I typically use a single loco. On the current BC&SJ I often assign a Bachman Spectrum USRA 2-10-2 light as helper (which adds another 14 or 15" to the train length so now its out to around 18').
An 18' train looks pretty decent on my current layout. It's long enough so that when you're railfanning it starts to feel like "when is this train gonna end!" which is about the right length (to me anyway).
To make this ok I've tried hard to keep towns separated by some distance. On the current layout Mill Bend and Oakhill are a bit over 50' apart. Running at the track speed (for helpers) of 20mph it takes about 5 minutes to leave Mill Bend, travel up the 2.8% grade and pull into Oakhill. Between Oakhill and the temporary Salem is only about 20 feet or so but if I get it to fully built there will be over 40' from Oakhill to Bear Creek Yard (on the peninsula).
On my previous layout I also was trying to keep the towns as far apart as possible. If I'd built it to completion towns would have averaged around 35' (or a bit more apart).
There are two things nice about 'distant' towns:
1) it takes a lot more time to get between the towns making the run feel a bit more realistic to the crews. To me distance should be measured in minutes of travel time when operating at the appropriate scale speed. Ideally I'd like a 'distance' of between 5 and 10 minutes separating towns. This can either be a longer run with higher speeds or a shorter run with lower speeds
2) there are fewer towns which means fewer structures to build/buy
Drawbacks to 'distant' towns are:
1) Since I'm modeling western Oregon there are TONs of trees required to fill in all that scenery space
2) there are fewer towns
3) need more layout for a given number of towns
Overall I think the town spacing I have now works fairly well but I've got a close to 1100 sqft train room. The previous layout occupied a 328 sqft footprint so it was heavily multi-decked to get enough mainline length. There is a temptation to add more decks but I'd recommend doing practical research before embarking on an ambitious contruction project - that is, find people who have multi deck layouts and visit them (and if possible join an op session on them). Pick their owners brains about construction techniques and little details like how did they decide to build which deck first - once a deck is in place it will interfere with constructing the deck above or below it - think in terms of wiring on an upper deck or installing track/scenery on a lower deck!
I hope this helped,
Charlie
