The exclamation point is for me. This is a reward for previously NOT thinking.
Problem:
Rolling stock would derail at a specific point – no evidence of rail damage.
Reason for derailing:
Rails had closed into each other a very slight bit from damaged ties.
Former remedy: Remove the damaged ties and bend the new tie plate holding “ears” back in order to press the new ties in place – then try and return the bent plastic to secure the rail.
Not the best answer.
NEW remedy:
Cut the outside plate “ears” off the replacement ties leaving just the inside ears undamaged. Spread the track rails enough to side the new ties up into place. The compression against the inside ears will keep the track at the right width.
Worked!
To be certain of holding power, I applied some PL construction glue to the outside of the rail at the points where the previous plate “ears” were.
The problem ties were early Aristo. The LGB have held up for over 10 years.
