As part of Loader V5 we took the decision to withdraw the old EXE simulations. We do not feel they reflect SimSig accurately as a product set because they are so old (10 years or more in some cases). Some of those simulations are being re-developed for Loader use, such as Edinburgh, so be on the look out for such releases. Generally, support has also ended for those simulations.
We realise this may be disappointing to some.
