Added rendering for PTC #77
Conversation
Added support for rendering North American Positive Train Control in the signal style.

Longer explanation: added code to render I took a look at the available tags here: the relevant tags are railway:acses, railway:ases, railway:etms, and railway:itcs, and railway:ptc. I did a tag usage survey and saw that railway:acses had 8 occurrences, and there were none for ases, etms, or itcs. There are currently 803 ways using railway:ptc. I added the railway:ptc tag to the 8 railway:asces nodes. There are several other PTC systems being approved including CBTC and e-ATC. Most of the freight network has adopted I-ETMS (railway:etms). ITCS was installed on one Amtrak line in Michigan. ACSES II (railway:acses) is used by Amtrak on the Northeast Corridor, connected branches, and by several commuter authorities that also operate on Amtrak-owned lines. ASES II is used on several New Jersey Transit lines. One line in Maryland has both I-ETMS and ASCES II so the commuter operator could simply use I-ETMS on all of their lines. It would be very complicated to add a color for each vendor's PTC implementation. Since most of these tags have never been used, it would be better to group everything under railway:ptc. If desired, a text layer could be added later to show the specific PTC implementation. |

Looks basically sane to me. Please rebase on current master. |

Please rebase to adapt to new changes in master. Tell us if you need any help. |

Hi! I took the liberty to do the rebase, unfortunately I had to open a different PR from my repo but I retained the original author. See #86. |

Sorry, I don't have time to be active right now. Thanks to all who are pushing this through! |
