... be a pain... Then again- I have taken over 1k pics in one day on some trips- and my shoulders get to ache when I do that... Anyway... 3017_121752_240000000.jpg Notice that the sole plate for the first set of blades has a block of steel welded onto it outside each slide chair- to prevent it from being forced outwards and out-of-gauge. This is standard practice for points... Next- an enlargement of the second set of blades... 3017_121757_520000000.jpg The insulated joint in the split sole plate is clear- as is the block of steel at the right hand side outside the chair- which doesn't appear to be a slide chair... The next chair further away appears to be the first slide chair- with the end of the blade on it... On the left hand side the left hand blade ends on the slide chair on the sole plate... Is there then a block welded on the sole plate between the two left hand rails? ...
