Thanks for your prompt answers.
TTDP+ doesn't work with OpenTTD anymore because it's not correctly formatted. See this link for more info: viewtopic.php?t=73464
I don't think this is the link you wanted to post, because it redirect me to a topic where we are talking about where to find the "vehicle never expire" option. Can you check please ?
Shame it doesn't exist anymore : there were great engines that are not in OpenGFX+ Trains ...
There is a Logic Engine in the NUTS Unrealistic Train Set , don't know if that is the GRF your looking for .
Yes, I know this one but this is not the one I want : I want to attach wagon or locomotives behind it and the one in NUTS doesn't attach to anything other that ... other logics engines.
(Briefly, I want to "exploit" its enormous power to reduce the distance between my train, especially with Maglev (Chimera is fast but its acceleration is very slow ...))
