Turnout inspection, check rail gauge , back to back distance, switch rail wear, frog wear and inspection, what else ?
Why is the frog bit called a frog?
For an existing layout you also need to check all bolts are correctly torqued and atleast 3 threads beyond the nut. Stretcher bars are in position, not damaged and bolts tight (ditto for bolts throughout layout) There may be Insulated Block Joints ,(IBJ's), check for wear and lipping to prevent track circuit issues. If any twist rails, twists are in correct bed, or if an older layout actually installed. Welds are located in centres of beds, any fishplated jpints are centre of bed and gaps correct for temperatures. Bearers are still square and not twisted which could cause gauge problems. Any misalignments especially at Heel locations if fixed heel blocks fitted, or where Ball and Claw there is still a gap either side of the ball (should not sit tight) Are correct components fitted for layout type (maintenance sometimes have to force different plates, or rails etc to fit. Any adjustment switches protecting layout, the ovetlaps are correct for temperature, and lubricated. Slide baseplates lubricated, if rollers fitted they are still set correctly. Are components fitted correct for layout type or has it been changed by during life of unit. Rail lengths check, joints in correct beds. Clips etc not missing. Does it look right.
It looks similar to the frog part of a horses hoof
Wedges/ check to make sure stock rail is fully seated in plates
That's probably Heel instead of Heal?
Very well
Guard rail or check rail?
Flangway gap Gauge at point of switch Flangway at frog point Hogging of switch Switch wear damage
Cos it looks like a frog swimming
