Detailing ideas ...
The PC&L #16 is admittedly a bit "cluttered" ... the crew has a theory that it makes them look busy and somehow pleases the boss. Use what you can find & vary to suit your tastes!
I've included some close-up photos and a list of the detail parts used on PC&L #16 to provide some ideas. Don't go nuts trying to find the exact same parts -- there are plenty of O scale detail items out there ... check with your favorite dealer for additional ideas.
Figures shown: Arttista #1175 Another Engineer and #1306 Brakeman Holding On. Note -- the engineer figure was cut near the waist with a cut-off disk in a motor-tool. The metal castings are very hard -- wear goggles to protect your eyes against flying metal bits (really!).
Dogs: Arttista #1131 Two Dogs ... yes, I'll add water bowls!
Bell: Grandt Line #105; cord made from .012" brass wire curved with finger tips and set into small hole drilled in cab front.
Bucket with Brush: From "Gilbert Gibi Creations" in Switzerland; picked that up at a train show -- Berkshire Valley and Mile Post Model Works have a variety of castings for buckets & such.
Buck Saws: Evergreen Hill Designs #EH8014 Hand Buck Saws.
Chain: Some leftover Builders-in-Scale chain, not currently in production. Check with your dealer and/or model ship suppliers for suitable chains.
Hand Tools: Berkshire Valley #577 Tool Set A (hammers/pliers), #578 Tool Set B (shovels), #579 Tool Set C (picks/axes) and Evergreen Hill Designs #EH8035 Wrench and File set.
Hydraulic Jacks: Mile Post Model Works #2936 Hydraulic Pump Jack.
Leather Tool Bag: Mile Post Model Works #3866 Carpenter's Tool Bag.
Lettering: from various Woodland Scenices dry transfer letter & number sets.
Metal Toolbox: Casting by Keith Wiseman (available from Caboose Hobbies); I believe the shovel standing upright is also a Keith Wiseman casting -- check his range for other hand tools.
Milk Can: Evergreen Hill Designs #EH8059 Milk Cans.
Oil Bottles: Berkshire Valley #559 Oil Bottles.
Water Cooler: Mile Post Model Works #2805 Water Cooler.
Weathering Chalks: Various shade of brown, gray, black, white and yellow were added to weather the loco. You can get an inexpensive set of pastels (regular, not oil-based) at the local craft store. Use sandpaper to make powdered chalk & apply with soft brushes. (Special chalks are also available for model railroaders.)
Wood Toolboxes: BVM #404 Wood Toolboxes (4/$3.00)
